A randomized clinical trial of two emergency contraceptive pill regimens in a Ugandan population

Abstract Background. Recent trials on emergency contraception (EC) have indicated that levonorgestrel (LNG) used alone has fewer side-effects and is more efficacious than the Yuzpe regimen (high dose combined oral contraceptive pills).
