See table 1 notes for definition of modern contraception. Short-term postpartum outcomes as defined as 63 days after the EDD. Survey outcomes are constructed using all available survey data in the relevant time window and may include surveys scheduled for 9 weeks, 3, 6 or 9 months or 1 year after the participant's EDD. Panel C describes characteristics of first initiation of modern contraception at any time in the postpartum period (within 1 year of delivery). The reduced sample size for cost of modern contraception is due to observations for which information on first modern method initiated was collected at the 3-month follow-up survey only; this survey did not include information on cost of current method if method not obtained at a health facility.
