Publication bias occurs if the results from studies which have not been published are different from the published ones. From a Bayesian viewpoint, it also concerns non-publication of studies with similar results as the published ones because the strength of the evidence will be influenced. Publication bias complicates…

Study coding is an essential component of the research synthesis process. Data extracted during study coding serve as a direct link between the included studies and the synthesis results, allowing reviewers to justify claims about the findings from a set of related studies. The purpose of this tutorial is to provide au…

An overview of systematic reviews with meta-analysis was developed to summarize evidence on the effectiveness of prenatal yoga-based interventions on pain, psychological symptoms, and quality of life during pregnancy. CINAHL (via EBSCOhost), Embase, PubMed, SPORTDiscus (via EBSCOhost), and the Cochrane Library were sea…
