Challenges of conducting a placebo-controlled trial for dysmenorrhea in adolescents.
Academic Article
Overview
abstract
We recruited adolescents to study oral contraceptives versus placebo for dysmenorrhea. We anticipated high discontinuation and concerns about safety, side effects, and sexual behavior. Treatment discontinuation (11%) and loss to follow-up (1%) were lower than expected. The most common reason for nonenrollment was logistical issues (63%). Most participants remained abstinent.
