aPercentages based on total number of live births. bEstimated from a Logistic Regression model. Saline is the reference group. cModel adjusted for the following covariates: breast-feeding difficulty history, body mass index, incision site, miscarriage history, and smoking status. dModel adjusted for miscarriage history. eModel adjusted for the following covariates: current alcohol consumption, race, and smoking status. fModel adjusted for covariate of race. gModel adjusted for education level.
