^a Data shown are odds ratio (95% confidence interval) and number (percentage);

^b Odds ratio expresses the likelihood that mothers will exclusively breastfeed their babies before discharge in the planned CDMR group compared to that in the planned VD group;

^c Odds ratio expresses the likelihood that mothers will formula feed their babies before discharge in the planned CDMR group compared to that in the planned VD group;

^d Adjusted for maternal age at delivery, BMI, gestation, infant birthweight, year of delivery, occupation, educational level, delivery hospital level, infant sex, mother's hospital stay before discharge, and location of residence or site of delivery or both.
