Criteria are presented to assist in the critical appraisal of investigations into the efficacy of therapy for low-back pain. Potential sources of statistical noise and experimental bias are identified in the selection of subjects, the application of therapy, and the evaluation of outcomes. When these criteria were applied to a series of recent articles, published in this journal, only two valid randomized controlled trials and four properly controlled cohort studies were found out of 147 reports.
本文提出了一些标准，以协助对腰痛治疗效果的调查进行批判性评估。在受试者选择、治疗应用和结果评估中识别出统计噪声和实验偏差的潜在来源。当将这些标准应用于该杂志最近发表的一系列文章时，在147篇报告中仅发现了两项有效的随机对照试验和四项恰当对照的队列研究。
