METHODStudies包括在四个荟萃分析检索和他们的研究设计evaluated. METHODTheMeta-analysis比较效果大小从不同的研究,不均匀盲,随机,对照,或高质量的。这些研究没有直接解决比较疗效的问题或缺乏检测sensitivity. CONCLUSIONSMany类型的研究需要谨慎评估荟萃分析的结论,而不是首先严格审查纳入的研究。当几乎完全基于间接的、多重混杂的比较时,不同治疗的相对疗效的估计没有很好的依据。基于有缺陷的研究或缺乏已证明的检测灵敏度的研究的荟萃分析也不足以批评治疗指南。一些数据不足以支持适当的荟萃分析。
OBJECTIVEThe author sought to illustrate the invalidity of meta-analyses that claim to quantitatively compare the benefits of psychotherapy to pharmacotherapy in patients with psychiatric disorders.METHODStudies included in four meta-analyses were retrieved and their study designs evaluated.RESULTSThe meta-analyses compared effect sizes from disparate studies that were not uniformly blind, random, controlled, or of high quality. The studies did not directly address the comparative efficacy question or lacked assay sensitivity.CONCLUSIONSNumerous types of studies exemplify the need for caution in evaluating meta-analytic conclusions without first critically examining the included studies. Estimates of the relative efficacy of different treatments are not well founded when based almost exclusively on indirect, multiply confounded comparisons. Meta-analyses based on flawed studies or studies that lack demonstrated assay sensitivity are also inadequate for the criticism of treatment guidelines. Some bodies of data are inadequate to support a proper meta-analysis.
