  1. NA Not assessed if less than 5 cases to minimize identifiability of individuals
  2. aAdjusted for maternal age, calendar year, and educational level. If there were ≤ 10 events in the exposed or unexposed groups, models were only adjusted for age and year. Preeclampsia/eclampsia was further adjusted for body mass index and smoking status
