Abstract

Randomized controlled trials (RCTs) are the gold standard in terms of study design, however, in the surgical setting conducting RCTs can often be unethical or logistically impossible. Case-control studies should become the major study design used in surgical research when RCTs are unable to be conducted and definitely replacing case series which offer little insight into surgical outcomes and disease processes.

摘要

随机对照试验（RCTs）在研究设计方面是金标准，然而，在外科手术环境中进行随机对照试验往往不道德或在后勤上不可行。当无法进行随机对照试验时，病例对照研究应成为外科研究中使用的主要研究设计，并肯定要取代病例系列研究，因为病例系列研究对外科手术结果和疾病过程几乎没有洞察力。
