Data, design, and background knowledge in etiologic inference

Epidemiology. 2001 May;12(3):313-20. doi: 10.1097/00001648-200105000-00011.

Abstract

I use two examples to demonstrate that an appropriate etiologic analysis of an epidemiologic study depends as much on study design and background subject-matter knowledge as on the data. The demonstration is facilitated by the use of causal graphs.
