Northern zone includes Upper West, Upper East and Northern regions; Middle zone includes Brong-Ahafo, Ashanti, Eastern and Volta regions; Coastal zone includes Western, Central and Greater Accra regions.
*MR or action to bring back a late period without necessarily knowing whether one is pregnant.
†Adjusted for missing confidantes and transmission bias.
‡Final estimate is the mean of the estimates from the three most valid approaches: direct reporting, confidante method and modified AICM. Instead of giving 95% CIs (which would risk overstating the certainty of this final estimate), we give lower and upper bounds based on the lowest and highest estimate (these are presented in the text).
AICM, Abortion Incidence Complications Method; MR, menstrual regulation.
