Selection in clinical research does not necessarily result in selection bias. To understand when selection leads to bias, we discuss collider-conditioning bias, which is a common and often self-inflicted type of selection bias. Collider-conditioning bias may be difficult to recognize, and paying more attention to the bias could therefore increase the quality of research. In this paper, we aim to increase awareness and understanding of the topic.
临床研究中的选择不一定会导致选择偏倚。为了理解何时选择会导致偏倚，我们讨论对撞机条件偏倚，这是一种常见且往往是自我造成的选择偏倚类型。对撞机条件偏倚可能难以识别，因此更多地关注这种偏倚可以提高研究质量。在本文中，我们旨在提高对该主题的认识和理解。
