The randomised placebo-controlled trial (RCT) is the gold standard for the evaluation of medical interventions. Observational studies, on the other hand, usually do not get much credit. For studies investigating surgical interventions this does not always seem entirely justified. A more refined approach might be needed for the often-used hierarchical structure of research designs. Instead of a strict separation of results from RCTs and other designs, results of the different designs should rather be regarded as complementary to each other when evaluating surgical interventions in traumatology.
随机安慰剂对照试验（RCT）是评估医学干预措施的金标准。另一方面，观察性研究通常不太受认可。对于研究外科手术干预措施的研究而言，这似乎并不总是完全合理的。对于常用的研究设计层次结构，可能需要一种更精细的方法。在评估创伤学中的外科手术干预措施时，不应将随机对照试验和其他设计的结果严格区分开来，而应将不同设计的结果视为相互补充的。
