In this issue of the Journal, Savitz and Wellenius (Am J Epidemiol. 2023;192(4):514-516) discuss the contribution of cross-sectional studies to causal inference when the data are used to address etiological research questions. We elaborate on their thoughts with a discussion of the conditions needed for addressing etiology with the cross-sectional design, using a modern causal inference lens.
在本期《美国流行病学杂志》中，Savitz 和 Wellenius（Am J Epidemiol. 2023;192(4):514-516）讨论了横断面研究在使用数据来解决病因学研究问题时对因果推断的贡献。我们用现代因果推断的视角，通过讨论使用横断面设计解决病因学问题所需的条件，进一步阐述了他们的观点。
