BACKGROUND: Rapid reviews are an accelerated evidence synthesis approach intended to meet the timely needs of decision-makers in healthcare settings. Quality of conduct and reporting has been described in the rapid review literature; however, no formal assessment has been carried out using available instruments. The ob…

BACKGROUND: Unilateral renal agenesis (URA) is associated with other congenital anomalies of the kidney and urinary tract (CAKUT) and extra-renal anomalies. However, the reported prevalences of these anomalies are highly variable. We estimated the prevalence of associated CAKUT and extra-renal anomalies in patients wit…

Esophageal cancer represents a substantial global health challenge, marked by poor prognosis, even after curative treatment. Health-related quality of life is crucial for evaluating the treatment efficacy and long-term outcomes in patients with esophageal cancer. This state-of-the-art review and evidence gap map sought…

BACKGROUND: The development of the web survey has led to significant strides in questionnaire survey methodology, including its potential to substantially increase sample sizes at minimal costs. Despite its advantages, web surveys typically achieve lower response rates from participants compared to more conventional su…

OBJECTIVE: To examine whether network meta-analyses, increasingly used to assess comparative effectiveness of healthcare interventions, follow the key methodological recommendations for reporting and conduct of systematic reviews. DESIGN: Methodological systematic review of reports of network meta-analyses. DATA SOUR…

Systematic review is a type of research that attempts to identify and summarize all of the evidence related to a specific research question. It can be thought of as a "pause" in the process of conducting research in a particular area, in which the following questions are asked: Based on all of the available evidence, w…

OBJECTIVE: This umbrella review was conducted to summarize the evidence and qualify the methodological quality of SR and SRMA published on small-sided games in team ball sports. METHODS: A systematic review of Web of Science, PubMed, Cochrane Library, Scopus, and SPORTDiscus databases was performed according to the Pr…

AIMS: The global rate of type 2 diabetes (T2D) continues to rise. Guidelines that influence the worldwide treatment of this disease are central to changing this trajectory.

OBJECTIVE: To simulate possible changes in systematic review results if rapid review methods were used. STUDY DESIGN AND SETTING: We recalculated meta-analyses for binary primary outcomes in Cochrane systematic reviews, simulating rapid review methods. We simulated searching only PubMed, excluding older articles (5, 7…

 To evaluate the impact of searching clinical trial registries in systematic reviews. Methodological systematic review and reanalyses of meta-analyses. Medline was searched to identify systematic reviews of randomised controlled trials (RCTs) assessing pharmaceutical treatments published between June 201…

BACKGROUND: The need for systematic methods for reviewing evidence is continuously increasing. Evidence mapping is one emerging method. There are no authoritative recommendations for what constitutes an evidence map or what methods should be used, and anecdotal evidence suggests heterogeneity in both. Our objectives ar…

OBJECTIVES: This study aims to examine the prevalence of comparisons of surgery to drug regimens, the strength of evidence of such comparisons and whether surgery or the drug intervention was favoured. DESIGN: Systematic review of systematic reviews (umbrella review). DATA SOURCES: Cochrane Database of Systematic Rev…

BACKGROUND: Recovery is a process involving empowering individuals to take control of their lives and develop meaningful and purposeful life, regardless of whether their mental health symptoms persist. Recovery-oriented practice has been widely implemented, particularly in Anglophone countries, during the past two deca…

The literature searches that are used to identify studies for inclusion in a systematic review should be comprehensively reported. This ensures that the literature searches are transparent and reproducible, which is important for assessing the strengths and weaknesses of a systematic review and re-running the literatur…

Manual therapy for neck pain enjoys a long history, with increasing popularity in recent times. The evidence base for manual therapies for neck pain consists of a reasonably large body of clinical trials, an even greater number of systematic reviews and, more recently, a number of practice guidelines. We have conducted…

This evidence-based study of the literature investigated the relationship between pacifier use (with and without sweetening and prolonged or short-term) and early childhood caries (ECC). The review was based on evidence from 3 main sources: a search of several electronic bibliographic databases, a review of the referen…

PURPOSE OF REVIEW: To understand the principles of systematic reviewing and meta-analysis, using recent examples from the medical literature to highlight some of these points. RECENT FINDINGS: The word 'meta-analysis' is an intimidating one, and its associated jargon makes it seem incomprehensible. Actually, it is onl…

BACKGROUND: The recommendations of experts who write review articles are a critical determinant of the adaptation of new treatments by clinicians. Several types of reviews exist (narrative, systematic, meta-analytic), and some of these are more vulnerable to researcher bias than others. Recently, the interest in nutrit…
