Unmeasured intermediate-outcome confounding as an explanation of the birthweight paradox: unmeasured common causes (U) of low birthweight (L) and infant mortality (Y), such as for instance malnutrition or birth defects, bias association between maternal smoking (S) and infant mortality.

Figure 2.
Outcome heterogeneity as an explanation of the birthweight paradox governing associations between maternal smoking (S) and infant mortality (Y) with: (a) two low birthweight phenotypes as ‘predominant’ (L1) and ‘residual’ (L2); (b) collapsed into one low birthweight category (L); (c) with a possible unmeasured confounder (U) of L2 and Y.
