Directed acyclic graphs describing the structure of collider stratification bias. (A) By conditioning on the collider (C) and not conditioning on all unmeasured common causes of C and Y, a noncausal path between X and Y is opened via X--U→Y. (B) Collider stratification bias in the association between childhood maltreatment and adult BMI at 2 time points (0 = baseline, 1 = 5-year follow-up) among a sample of older adults with chronic illnesses. Additional covariates included in the final regression model were not included in the directed acyclic graph for simplicity. The red dashed lines indicate the spurious association created by conditioning on a collider. BMI, body mass index.
