The control group intervention was the axillary block in 14 studies, supracla... | We searched the databases until June 2013, and included 22 studies involving 1732 patients of whom 842 had an infraclavicular block and 930 had brachial plexus blockade with another technique. These other techniques were axillary block (injection in the armpit area; 14 studies), supraclavicular block (injection in the ... |
We identified six eligible studies in total. The six Included studies were generally of high quality, but the largest eligible study was excluded because of concerns about its validity. Study populations were statin naive, which led to a considerable loss of eligible participants. Five RCTs compared statin use with pla... | In July 2012 we searched medical databases for controlled trials of participants who had undergone aortic or arterial surgery and were randomly assigned to either statins or placebo (or standard care). Many vascular surgery patients are already taking statins; therefore we also included trials that randomly assigned pa... |
Ten trials involving 10,479 participants were included. There was inconclusive evidence of an effect on the proportion of participants with index case management (defined as individuals tested, diagnosed and treated for CT or NG, or both) in the group with home-based (45/778, 5.8%) compared with clinic-based (51/788, 6... | We searched the available literature for trials in which people were invited either to collect specimens at home or to attend a clinic for collection of specimens. We found 10 relevant trials in total. Three trials (including 1566 people) provided data to assess the proportion of people who completed testing, diagnosis... |
Four studies in 170 participants compared antidepressant therapy (fluoxetine, sertraline, citalopram or escitalopram) versus placebo or psychological training for 8 to 12 weeks. In generally very low or ungradeable evidence, compared to placebo, antidepressant therapy had no evidence of benefit on quality of life, had ... | We included all studies which have looked at drug treatment against placebo (sugar pill) or other kinds of mental health support. People included in the studies had an equal chance of receiving either treatment. Unfortunately, even though depression is very common and finding good treatments for depression are highly v... |
We included 244 randomised clinical trials with 28,619 participants that met our inclusion criteria. We considered all trials to be at high risk of bias. Two trials accounted for one-third of all included participants. The included participants were heterogenous with regard to disease (20 different medical specialties)... | We included 244 trials, with 28,619 participants. The included trials assessed the effects of different kinds of nutrition support (i.e. dietary advice, enriching regular food with extra protein and calories, protein shakes, feeding through a catheter directly into a vein or through a tube directly into the stomach or ... |
Five trials with 1838 randomised patients were included. There is some evidence for improved overall survival after treatment with purine antagonists compared to alkylators, but statistical significance was not reached (HR 0.89 [95% CI 0.78 to 1.01], 4 trials, N = 1638). However, the relative risk for achieving an over... | This review confirms the greater response rates achievable by using purine antagonists but at the cost of greater toxicity, mainly infections. There is inconclusive evidence whether treatment with purine antagonists improves survival. None of the studies included quality of life data. More research is needed to fully e... |
Twenty two trials (3707 patients) were included. Hb ≥ 133 g/L was not associated with a reduction in the risk of all-cause mortality compared with 120 g/L in dialysis and pre-dialysis patients. In pre-dialysis patients, there was a significantly lower end of treatment creatinine clearance with Hb < 120 g/L compared to ... | This review of clinical studies found that increasing haemoglobin to high levels lowered the chance of a person having a seizure, but increased blood pressure. Haemoglobin levels above 133 g/L did not reduce the risk of death in people with heart and kidney disease. |

All three trials recruited participants aged 60 years or younger with a cryptogenic stroke or minor stroke and had a PFO diagnosed by specialist heart scan. 1150 participants wer... |
We included 19 studies (1756 participants). We selected only randomized, placebo-controlled, double-blinded studies to minimize inclusion of poor quality studies. However, the risk of bias in the included studies was not formally assessed. Children receiving a single intraoperative dose of dexamethasone (dose range = 0... | We included 19 randomized controlled trials in the review, with a total of 1756 patients. The review of trials found that a dose of corticosteroid during tonsillectomy or adenotonsillectomy can prevent vomiting for one out of every five children who gets the drug. Children also return to a normal diet more quickly and ... |
Two studies with a total of 84 participants were included: a 12-month RCT of early rehabilitation in adults of mean age 72 years conducted in two centres in England (UK) and a six-month proof-of-concept RCT of an expert patient programme (EPP) in adults of mean age 60 years in a single regional respiratory centre in No... | We conducted a search on 13 December 2017 and found just two UK studies that included 84 participants, comparing a self-management approach with normal care for adults with bronchiectasis. One study looked at the impact of an expert patient self-management programme and the other, involving just a small number of parti... |
We included 21 studies (6016 participants) in this review. Trimethoprim-sulfamethoxazole (TMP-SMX) was as effective as fluoroquinolones in achieving short-term (RR 1.00, 95% CI 0.97 to 1.03) and long-term (RR 0.99, 95% CI 0.94 to 1.05) symptomatic cure. Beta-lactam drugs were as effective as TMP-SMX for short-term (RR ... | Twenty one good quality studies, enrolling 6016 participants, which used different classes of antimicrobials for treating acute cystitis in women for 3 up to 10 days, were included in this review.

We included a single-centre non-blinded randomised controlled trial that reported a total of 302 intubation attempts in 232 infants. The median gestational age of enrolled infants was 29 weeks. Paediatric residents and fellows performed the intubations. We judged the study to be at low risk of bias overall. Investigato... | In literature searches updated in April 2017, we found one randomised controlled trial (302 intubations) that met the inclusion criteria of this review. Rates of successful intubation at first attempt with or without use of a stylet as an aid were similar, at 57% and 53%, respectively. Success rates with and without us... |
For abdominal wall lift with pneumoperitoneum versus pneumoperitoneum, a total of 130 participants (all with low anaesthetic risk) scheduled for elective laparoscopic cholecystectomy were randomised in five trials to abdominal wall lift with pneumoperitoneum (n = 53) versus pneumoperitoneum only (n = 52). One trial whi... | A total of 130 participants (all with low anaesthetic risk) were included in five trials which compared abdominal wall lift combined with very low pressure pneumoperitoneum and standard pneumoperitoneum. All five trials had a high risk of bias (introducing the possibility of overestimating benefits or underestimating t... |
We included 13 studies, with a total 467 participants, testing a range of different interventions. Outcome measures included 36 measures of sensory impairment and 13 measures of upper limb function. All but two studies had unclear or high risk of bias. While there is insufficient evidence to reach conclusions about the... | We found 13 studies involving 467 participants that tested different treatments for sensory loss. There is limited evidence that these treatments may be effective. No more than one study examined each particular intervention, frequently the studies were of poor quality and lacked sufficient information. Further researc... |
Nine trials involving 1822 patients with bleeding haemorrhoids were identified. The included trials were generally not of high quality and used one TCMH preparation compared with another TCMH preparation (Type I) (five trials) or western medicines (Type II) (four trials). We could not pool the data to perform a meta-an... | However, our primary research for this review showed that there was no strong evidence concerning the effectiveness of TCMHs in stopping bleeding from haemorrhoids. The included studies were few and of low quality. Limited, weak evidence showed that some formulae, when including Radix Sanguisorbae, Radix Rehmanniae, Fr... |
We included two RCTs (1167 participants). The first RCT compared zoledronic acid with placebo in 96 men undergoing pelvic radiotherapy for non-metastatic prostate cancer. The second RCT had four treatment arms, two of which evaluated zoledronic acid plus adjuvant androgen suppression compared with androgen suppression ... | We found two studies where people were randomly put into one of two or more treatment groups (called randomised controlled trials) which were sufficiently relevant to the review topic. Both studies, which involved 1167 participants altogether, were conducted in men undergoing radiotherapy for prostate cancer and evalua... |
The overall quality of the evidence was very low. In this update no new studies were identified for inclusion; one additional study was excluded. Of the two small included studies, one study showed a non-significant effect of calcitonin on the number of patients with complete pain relief (risk ratio (RR) 2.50; 95% conf... | This review looked at the effectiveness of calcitonin for controlling pain from bone metastases. However, only two studies were found with very low quality evidence to support the use of calcitonin for patients suffering from bone pain. We updated the review in 2015 and did not find any more studies. There were slightl... |

Seven studies mostly with small sample sizes, comparing 4 different interventions (prostaglandins alone, mifepristone alone, and mifepristone/misoprostol and methotrexate/misoprostol versus vacuum aspiration) were included. Results are sometimes based on one trial only. Prostaglandins vs vacuum aspiration: the rate of... | The review of trials found that medical methods for abortion in early pregnancy can be safe and effective, with the most evidence of effectiveness for a combination of mifepristone and misoprostol (a prostaglandin). Almost all of the trials were done in well-resourced hospitals where women returned for check-up. |
Among 409 retrieved references, we identified 16 RCTs; six of them, published between 1987 and 2007, met the selection criteria and were included in this review. Five hundred and forty RR patients and 1049 PMS contributed to the analysis. In RR MS, a decrease in the mean EDSS score (-0.33 and -0.45), was found respecti... | Previous studies indicate that glatiramer acetate, a synthetic drug, is effective in animal models of MS, and shows some benefits in MS patients. The objective of this review was to assess the efficacy of glatiramer acetate in RRMS and PMS patients. Among the pertinent medical literature six studies met the criteria of... |
The 2005 update includes a new trial (Kuriyama 2002) to bring the total of included studies to three (total n=33). One study, which used a cross-over design (Tolbert 1993) provided insufficient data to conduct an analysis. Another crossover study (Findling 1997) yielded no significant differences between treatment and ... | Studies investigating the effect of vitamin B6 in improving the behaviour of children with autism spectrum disorder have been reported for over three decades. The purpose of this review was to summarize those studies and analyse the effectiveness of vitamin B6 as an intervention. Only three studies met the inclusion cr... |

This review of randomised clinical trials suggests that... |
Two studies (involving 286 women) from amniocentesis (but none from CVS) compared the impact of communicating results of rapid testing with waiting for definitive karyotype. Unfortunately, it was not possible to perform pooled analysis because one study reported only median (interquartile range) data, presumably becaus... | One study reported a statistically significant reduction in the average anxiety during the waiting period for women who had had a rapid test, but the other found no difference between the two groups. There was also no evidence to support the view that issuing amniocentesis results as soon as they are available is more ... |
We include 10 RCTs (n = 1850); almost all participants had moderate or severe ARDS. For the primary analysis, the risk of bias was low in three studies and unclear in five studies; the overall quality of evidence was very low due to imprecision, inconsistency, indirectness and methodologic limitations. In participants ... | We included 10 randomized controlled trials (RCTs) enrolling 1850 participants in this updated review. One large trial was stopped early because of increased deaths among participants who were randomized to HFO. Four trials reported at least some funding from manufacturers of HFO ventilators. HFO did not reduce the ris... |
We included six RCTs (692 participants). The overall risk of bias in the studies was low. Two studies assessed oral administration of tranexamic acid, given regularly over several days, and compared it to placebo. In the other four studies, a single application of topical tranexamic acid was compared with placebo (one ... | We searched for randomised controlled trials in patients of any age with nosebleed requiring intervention.

We included seven studies (662 participants) in this review. All except one study was assessed as being at high risk of bias. Three studies assessed atorvastatin, three assessed simvastatin and one investigated rosuvastatin. All studies collected data during the immediate perioperative period only; data collection to h... | This review aims to evaluate evidence on the use of statins at the time of heart surgery to investigate if use can help to prevent kidney failure and how well statins are tolerated among patients. We searched the literature to January 2015 and included seven studies that involved a total of 662 participants to inform o... |
Nineteen trials involving 10,667 women were included. Risk of bias in trials was difficult to assess accurately due to incomplete reporting. None of the evidence relating to our main outcomes was graded as high quality. The quality of evidence was downgraded due to missing information on trial methods, imprecision in r... | We searched for evidence in March 2017. We found 19 trials involving over 10,000 women. Eighteen of these studies compared the use of Doppler ultrasound of the umbilical artery of the unborn baby with no Doppler or with cardiotocography (CTG, sometimes called electronic fetal monitoring). One more recent trial compared... |
We identified nine RCTs (587 participants) for inclusion in the review, of which three studies were found at this update. The sequence generation was inadequate in one study and not described in three studies. We performed two meta-analyses to evaluate the clinical (3 trials, 261 participants) and neurophysiological (2... | We found two randomised controlled trials (RCTs) of nonsurgical treatment. One RCT compared three groups of people with mild or moderate UNE (51 people in total). All three groups received written instructions to avoid movements or positions that provoked symptoms. The second group had the same information with elbow s... |
We included 10 trials with a total of 3417 women randomised. Seven of these trials, recruiting 2629 women, contributed data to the review. However, results for all outcomes were based on single studies. There was limited evidence for the primary outcomes of reduction of episodes of violence (physical, sexual, and/or ps... | Routine prenatal care offers opportunities for healthcare staff to identify women at risk of being abused. In this review we included 10 randomised trials involving a total of 3417 women, seven of which studied pregnant women who were at high risk of partner violence. The interventions examined in the studies included ... |
Twelve trials were included (2514 patients, average follow-up six years), 11 using selegiline. The methodological quality was reasonable although concealment of allocation was definitely adequate in only five trials. MAO-B inhibitors were not associated with a significant increase in deaths (odds ratio (OR) 1.12; 95% c... | We reviewed 11 controlled trials with a total of 2514 patients that compared giving MAO-B inhibitors with not giving them in people with early Parkinson's to see if it was safe and effective. The results show that, although MAO-B inhibitors do improve symptoms of Parkinson's and delay the need for levodopa by a few mon... |
We included 14 RCTs that evaluated a range of interventions across different settings. The study methods were generally poorly described, and consequently all included trials were judged to be at high or unclear risk of selection and reporting bias. Only seven trials reported clinical outcome data which limits our abil... | This review summarises trials evaluating different measures to prevent leishmaniasis. After searching for relevant trials up to January 2015, we included 14 randomized controlled trials. What is vector and reservoir control and how might they prevent leishmaniasis? Leishmaniasis is a group of infectious diseases caused... |
The search resulted in 524 potentially relevant articles. Five eligible randomized controlled trials (RCTs) were identified (305 women). Trials using oral tablets, transdermal patches and implants were identified. No trial used gels. One small cross-over trial (11 women, effective sample size 22 women considering cross... | The review identified 524 potentially relevant articles. Only five randomized controlled trials met our inclusion criteria, and these compared oestrogen with placebo in a total of 305 women who were clinically diagnosed with PMS. We found very low quality evidence to suggest that oral unopposed oestrogen given in the l... |
We included six small trials involving 244 adults with olecranon fractures. Of these, four were RCTs and two were quasi-RCTs; both of were at high risk of selection bias. All six trials were at high risk of performance bias, reflecting lack of blinding, and four trials were at high risk of detection bias. The quality o... | All six trials were small and had weaknesses that could affect the reliability of their results. We judged the overall quality of the evidence available for each comparison as either low or very low. One trial compared the use of plate fixation with tension band wiring. It found that more people had pain-free elbow mot... |
Thirty-four trials (3230 participants) were included. Meta-analysis showed that the mean change in urinary sodium (reduced salt vs usual salt) was -75 mmol/24-h (equivalent to a reduction of 4.4 g/d salt), the mean change in BP was -4.18 mmHg (95% CI: -5.18 to -3.18, I2=75%) for systolic and -2.06 mmHg (95% CI: -2.67 t... | Our pooled analysis of randomised trials of 4 weeks or more in duration shows that such a reduction in salt intake lowers blood pressure both in individuals with raised blood pressure and in those with normal blood pressure. The fall in blood pressure is shown in both whites and blacks, men and women. Additionally, our... |
Investigators included 6201 participants in the 51 included trials. Twenty studies included only children, two included only preschool children and ten only adolescents; all others included both children and adolescents. Participants were exposed to sexual abuse in 12 trials, to war or community violence in ten, to phy... | Children and adolescents receiving psychological therapies were less likely to be diagnosed with PTSD and had fewer symptoms of PTSD up to a month after treatment compared with those who received no treatment, treatment as usual or were on a waiting list. Our confidence in these findings is limited as the overall quali... |
In the initial review, we included one ITS study that evaluated a targeted educational intervention aimed at reducing the incidence of wrong-site tooth extractions. The intervention included examination of previous cases of wrong-site tooth extractions, educational intervention including a presentation of cases of erro... | This updated review contains two interrupted-time-series (ITS) studies (studies in which data are collected at multiple time points before and after an intervention), one from the original review, which evaluated a targeted educational intervention aimed at reducing the incidence of wrong-site surgery, and which was fo... |
Five studies (182 children) met the inclusion criteria, and four contributed data to at least one meta-analysis. The included studies were overall at low risk of bias, but our confidence in the evidence was generally low, mainly due to the small sample sizes. Treatment with IV MgSO4 reduced the odds of admission to hos... | We found five studies in children that compared an infusion of MgSO4 to a placebo infusion when other treatments had not relieved the attack (usually inhaled bronchodilators, steroids, and sometimes oxygen). These five studies included a total of 182 children. Only three of the studies reported the outcome we were most... |
We included 12 trials (576 participants); 11 had two arms and one had three arms. All assessed topical agents, none looked at systemic antibiotics. The included trials assessed the following antimicrobial agents: povidone iodine, cadexomer iodine, gentian violet, lysozyme, silver dressings, honey, pine resin, polyhexan... | In October 2015 we searched for as many studies as we could find that were randomised controlled trials and compared the use of an antibiotic or antiseptic with other treatments for pressure ulcers. We found 12 trials involving a total of 576 participants. Most study participants were older people in hospital. Most ulc... |
Three trials with 102 participants were identified and met the criteria for inclusion in this review. These trials compared stilboestrol to placebo, sildenafil to placebo and ephedrine or etilefrine to placebo and ranged in duration from two weeks to six months. All of the trials were conducted in an outpatient setting... | We found three trials set in Jamaica, Nigeria and the UK involving 102 people. In the trials, four different drug treatments (stilboestrol, sildenafil, ephedrine and etilefrine) were compared to placebo. The trials all looked at whether the treatments reduced how often attacks of priapism occurred. There was no differe... |
Ten studies (6 randomised controlled trials and 4 prospective cohort studies, involving 955 participants) met the inclusion criteria for the review. We considered 7 of the 10 studies to be at high risk of bias in at least one of the domains we assessed. Nine studies compared an opioid antagonist-adrenergic agonist comb... | We identified 10 studies, including six randomised controlled trials (where people are randomly put into one of two or more treatment groups) and four prospective cohort studies (where participants could choose which treatment they received) involving 955 opioid-dependent participants. Four of the studies took place in... |
