Follow Up
Women in the clinical trial are followed through regularly scheduled examinations to ensure the timely ascertainment of updated medical histories, tomonitor the occurrence of possible adverse effects, to dispense study medications, and to promote adherence to the study protocol. Observational study (OS) participants are contacted annually by mail to obtain updates of their medical histories and selected exposure data. At about 3 years after enrollment, all OS participants are invited to a clinic follow-up visit to update selected baseline data, to obtain additional risk factor data, and to collect a blood specimen.
