¹Odds Ratio of breastfeeding practice (PC group vs Control group) at each time point.
²Exclusive breastfeeding since birth (Labbok's strict definition).
³Exclusive breastfeeding current status (Aarts' definition).
⁴p-value testing the difference in baseline breastfeeding practice between the PC and control groups after adjusting for having or not previous breastfeeding experience, primiparae or not, and working status (having or not worked in the last 12 months).
⁵ p-value testing the difference in change from baseline in breastfeeding practice between the PC and control groups after adjusting for having or not pervious breastfeeding experience, primiparae or not and working status (having or not worked in the last 12 months).
