چکیده
Critical Appraisal of ‘‘EvidenceBased Labor and Delivery Management’’ The ability to critically appraise research reports is an essential skill for contemporary health professional practice. This applies equally to reports of single studies and reviews described as ‘‘evidencebased’’. Review articles compile all relevant research ¢ndings into one place and help resolve varied or con£icting results of individual studies. However, reviews themselves are subject to bias. Of highest quality are systematic reviews, using meta-analysis to clarify uncertainty by increasing power and precision around estimates of effect. Narrative reviews also discuss and summarize the literature on a topic of interest, but do so without reporting or reliably applying pre-speci¢ed criteria. Due to their inherent subjectivity, narrative reviews are included in the same level of evidence as expert opinion. A comprehensive new guidebook for health professionals seeking to undertake or assess the quality of a review provides resources to identify potential bias and evaluate the quality of review recommendations (CRD, 2009).
