PurposeThis article introduces practicing urologists to the critical evaluation of systematic review and meta-analysis to guide their evidence-based clinical practice.Materials and MethodsUsing a urological clinical case scenario，we introduces a 3-step process in evaluating systematic review and meta-analysis by considering 1）the validity of the review results，2）what the results are，和3）结果可以和应该应用于患者护理的程度。ResultsA系统综述旨在综合关于特定临床问题的医学文献，使用明确的方法进行全面的文献检索，识别和选择合格的研究，批判性地评价他们的方法，并明智地总结结果，考虑它们如何随研究特征而变化。当这个总结涉及统计方法时，即荟萃分析，评论者可以提供一个汇总的估计，这将具有更高的精度，并且比单个研究适用更广泛。质量的基础研究，跨研究的结果的一致性和精度的汇总估计可以大大影响推理的强度从systematic reviews.ConclusionsValid高质量的研究的系统评价，可以增加信心，泌尿科医生和患者作出循证决策。因此，泌尿科医生需要认识到固有的局限性，了解结果，并明智地将其应用于患者护理。
PurposeThis article introduces practicing urologists to the critical appraisal of systematic reviews and meta-analyses to guide their evidence-based clinical practice.Materials and MethodsUsing a urological clinical case scenario we introduce a 3-step process in evaluating systematic reviews and meta-analyses by considering 1) the validity of the review results, 2) what the results are, and 3) the extent to which the results can and should be applied to patient care.ResultsA systematic review seeks to synthesize the medical literature about a specific clinical question using explicit methods to perform a comprehensive literature search, identify and select eligible studies, critically appraise their methods, and judiciously summarize the results considering how they vary with study characteristics. When this summary involves statistical methods, ie a meta-analysis, reviewers can offer a pooled estimate that will have greater precision and will apply more broadly than the individual studies. The quality of the underlying studies, the consistency of results across studies and the precision of the pooled estimate can considerably affect the strength of inference from systematic reviews.ConclusionsValid systematic reviews of high quality studies can increase the confidence with which urologists and patients make evidence-based decisions. Thus, urologists need to recognize the inherent limitations, understand the results and apply them judiciously to patient care.
