  • For dichotomous variables, the model compared the differences in the ORs for year 3 versus year 1 for the intervention and control groups. See “Methods“ for elements included in the model.

  • a Variable shows significant effect modification by gestational age (P = .03); overall results and results according to gestational age group are shown. The significance of interaction term is shown in parentheses.
