a
Differential association was indicated by significant interaction between the risk factor and pregnancy stage (early [trimester 1] vs. middle/late [trimesters 2 and 3]) in logistic regression. Since no interaction was significant (all p-values>0.05), results are not shown stratified by pregnancy stage.
b
Adjusted for trimester, age, race/ethnicity, education, income, marital status, and year.
