The name of the study should properly reflect the actual conduct and analysis of the study. This short paper provides guidance on how to properly name the study design. The first distinction is between a trial (intervention given to patients to study its effect) and an observational study. For observational studies, it should further be decided whether it is cross-sectional or whether follow-up time is taken into account (cohort or case-control study). The distinction prospective-retrospective has two disadvantages: prospective is often seen as marker of higher quality, which is not necessarily true; there is no unifying definition that makes a proper distinction between retrospective and prospective possible.
研究的名称应恰当地反映研究的实际进行和分析。本文简要介绍如何恰当地为研究设计命名。首先要区分试验（给予患者干预措施以研究其效果）和观察性研究。对于观察性研究，还需要进一步决定它是横断面研究还是考虑随访时间（队列或病例对照研究）。前瞻性-回顾性的区分有两个缺点：前瞻性通常被视为高质量的标志，但不一定如此；没有一个统一的定义可以对回顾性和前瞻性进行恰当的区分。
