STUDY DESIGN: In this Journal Club review, we critically examine the methodology and results of a recently published meta-analysis describing the time dependency of surgical outcomes associated with cauda equina syndrome (CES) diagnosis. OBJECTIVES: Our objectives are to clarify the strengths, weaknesses, and appropri…

OBJECTIVES: To study whether the reporting of clinical outcomes in arthritis trials measured on ordinal and interval scales is adequate in relation to meta-analysis. METHODS: Systematic review of randomised trials of non-steroidal anti-inflammatory drugs in patients with rheumatoid arthritis. Optimal reporting was def…

OBJECTIVE: To replicate and to critique a recently published meta-analysis[1] of the incidence of nonpreventable serious and fatal adverse drug reactions (ADRs) in hospitalized patients, to better understand its results and conclusions. METHODS: The published methods described in the meta-analysis of Lazarou and colle…

AIMS: To evaluate the effectiveness of home visiting programmes on parenting and quality of the home environment. DESIGN: Systematic review of the literature of randomised controlled trials and quasi-experimental studies evaluating home visiting programmes involving at least one postnatal visit. SUBJECTS: Thirty four…

Meta-analyses may become biased if the reported data in the individual trials are biased and if overlap among trials cannot be identified. We describe the unanticipated problems we encountered in collecting data for a meta-analysis comparing a new antifungal agent, fluconazole, with amphotericin B in patients with canc…

We describe a meta-analysis approach for the evaluation of a potential surrogate marker. Surrogate markers are useful in helping to identify therapeutic mechanisms of action and disease pathogenesis, and for selecting therapies to take forward from phase II to phase III clinical trials. They have also become increasing…

We performed a meta-analysis of 38 articles containing 66 treatment groups and 3443 patients in order to evaluate prognostic factors in advanced epithelial ovarian cancer. To evaluate overall survival we designed a method to summarize the overall survival curve into one single figure: the log (relative risk) (LRR). Thi…

BACKGROUND: Aphasia is one of the most common complications of stroke. Mirror therapy (MT) is promising rehabilitation measure for the treatment of post-stroke aphasia. Although some studies suggested that MT is effective and safe for aphasia, the effects and safety remain uncertain due to lacking strong evidence, such…

INTRODUCTION: Perineal trauma is one of the most common complications of childbirth, impacting approximately 9 out of 10 women who undergo a vaginal delivery. Perineal trauma is a public health issue leading to increased maternal morbidity and decreased quality of life. Although race is being studied as a potent…

INTRODUCTION: Although caesarean sections (CSs) are essential for the management of obstructed labour and other obstetric complications, postoperative pain, delayed recovery and complication risks continue to be significant challenges in perioperative management. Improvements in traditional medications and surgical tec…

INTRODUCTION: Osteoporosis is a skeletal condition with decreased bone mass and structural deterioration, increasing fracture vulnerability. Several studies have found a correlation between prostate cancer in men and an increased risk of osteoporosis. This study aims to determine the prevalence of osteoporosis in patie…

BACKGROUND: Many histopathologic prognostic markers, identified by routine hematoxylin and eosin (HE) staining, have been proposed for predicting the survival of patients with oral squamous cell carcinoma (OSCC). Subsequently, several meta-analyses have been conducted on these prognostic markers. We sought to analyze t…

INTRODUCTION: With an increasing incidence and significant effects on patients, tinnitus has become a major disease burden. There is a dearth of therapies with established efficacy for tinnitus. Transcutaneous auricular vagus nerve stimulation (ta-VNS) is being investigated as a potential therapy for tinnitus, but the…

We aimed to explore, in a sample of systematic reviews (SRs) with meta-analyses of the association between food/diet and health-related outcomes, whether systematic reviewers selectively included study effect estimates in meta-analyses when multiple effect estimates were available. We randomly selected SRs of food/diet…

BACKGROUND: Knowledge about the risks of drugs during pregnancy is continuously evolving due to the frequent publication of a large number of epidemiological studies. Systematic reviews and meta-analyses therefore need to be regularly updated to reflect these advances. To improve dissemination of this updated informati…

BACKGROUND: The hippocampus has for long been known for its ability to form new, declarative memory. However, emerging findings across conditions in the psychosis spectrum also implicate its role in emotional regulation. Systematic reviews have demonstrated consistent volume atrophic changes in the hippocampus. The aim…

INTRODUCTION: The circadian rhythm of melatonin secretion is disturbed after general anaesthesia, leading to postoperative sleep disturbance. Small studies investigating the preventive effect of melatonin administration on postoperative sleep disturbance have not reached any conclusions. Therefore, we will conduct a sy…

OBJECTIVE: Lifestyle interventions have been shown to be both effective and cost-effective in reducing diabetes and metabolic risk in high-risk populations. We systematically reviewed the effectiveness and cost-effectiveness of lifestyle interventions on anthropometric, glycemic and cardiovascular outcomes in women wit…

OBJECTIVE: Model-based meta-analysis was used to describe the time-course and dose-effect relationships of antidepressants and also simultaneously investigate the impact of various factors on drug efficacy. METHODS: This study is a reanalysis of a published network meta-analysis. Only placebo-controlled trials were in…
