Establishing the overall efficacy or safety of a drug requires a unified methodological approach and analysis of all clinical trials to be included. As an example, this paper presents the aggregated dose-response relationship of efficacy data and a last-value analysis of laboratory data across all studies of the antihy…

Because individual studies evaluating the role of quinidine in the maintenance of sinus rhythm after cardioversion from chronic atrial fibrillation have involved relatively few patients, a meta-analysis of randomized control trials was performed. Six trials published between 1970 and 1984 were selected by two blinded r…

METHOD: We applied two different meta-analytical techniques (conventional meta-analysis and mixed treatment comparisons). Overall, 53 studies wit…

The objective of this study was to determine the effect of steroid therapy on pulmonary function, admission rates, and relapse rates in patients presenting with acute exacerbations of asthma. Computerized MEDLINE and SCIENCE CITATION searches were combined with review of reference lists from book chapters and articles…

The relationship between calcium intake and bone mass remains controversial. In this paper, the published research on this association is reviewed using the quantitative technique of meta-analysis. Selection of studies was based on defined eligibility criteria, and information relating to study design was recorded. Stu…

Quantitative methods were used to review epidemiologic data relating consumption of alcoholic beverages to risk of colorectal cancer. The data (27 studies) supported the presence of a weak association. For consumption of two alcoholic beverages daily, on average the relative risk of colorectal cancer was 1.10 (95% conf…

Multiple studies have demonstrated that individual psychotherapy, pharmacotherapy, and the two in combination are all effective treatments for depressed outpatients.

Studies of risk factors for Alzheimer's disease have been hampered by low statistical power. The data from 11 case-control studies were pooled and re-analysed to evaluate the evidence for the association of Alzheimer's disease with family history of dementia and related disorders, parental age, medical history, and env…

IMPORTANCE: Pediatric flexible flatfoot (PFF) is a common condition affecting children's foot biomechanics. While various conservative treatments exist, their relative effectiveness remains unclear. OBJECTIVE: The objective was to compare the effectiveness of non-surgical interventions-orthotic devices, active exercis…

INTRODUCTION: This study aimed to explore the efficacy and safety of neoadjuvant immunotherapy combination regimens in locally advanced resectable esophageal squamous cell carcinoma (ESCC), and evaluate the pros and cons of different regimens and their impacts on survival by integrating network meta-analysis (NMA) and…

BACKGROUND: Type 2 diabetes (T2D) management has shifted towards integrated cardiometabolic and renal risk reduction. Although glucagon-like peptide-1 receptor agonists (GLP-1RAs) and newer dual agonists show promising benefits, comparative evidence across agents and outcomes remains limited. OBJECTIVES: To compare th…

BACKGROUND: Prediabetes refers to the transitional stage from normal glucose metabolism to diabetes. The International Diabetes Federation guidelines reported that, as of 2024, approximately 1.12 billion people globally were in the prediabetes stage.

OBJECTIVE: This network meta-analysis (NMA) of randomized controlled trials (RCTs) evaluates the long-term efficacy and feasibility of treatments for macular edema (ME) secondary to retinal vein occlusion (RVO). Comparisons between different alternatives remain unclear. METHODS: We used a Bayesian framework to perform…

OBJECTIVE: To compare the efficacy and safety of four immunosuppressive therapies, either alone or in combination, for primary membranous nephropathy through a network meta-analysis.
