Repeat Use of Emergency Contraception in Kenya: Letter to the Editor

Contraception; 2011 Dec; 84(6):655-6; author reply 656; doi:10.1016/j.contraception.2011.03.025

This letter responds to an article reporting on a published survey of women purchasing emergency contraception (EC) at pharmacies in Kenya. One of the key findings of the article is the high number of women who had already used EC that same month. This letter identifies a sampling bias in the methodology that led to an overestimation of this finding. A reanalyzation of the survey data is suggested. (no abstract available)
