Time frame: Up to 1 year
Primary Efficacy Outcome measure for this study was contraceptive efficacy, or the prevention of in-treatment pregnancy. The total incidence of in-treatment pregnancies was expressed as the Pearl Index, which is defined as the number of in-treatment pregnancies per 100 woman-years of exposure (one woman-year defined as a period of 365.25 days).
Time frame: Up to 1 year
Participants kept diaries to record vaginal bleeding events. They were asked to record, on a daily basis, whether they experienced vaginal bleeding, which included BLEEDING or SPOTTING, at any time during a cycle other than normal menstruation while in the study. (This is also known as "breakthough" bleeding.) Vaginal bleeding that required >=2 pads/tampons per day was classified as BLEEDING. Vaginal bleeding that required <=1 pad/tampon per day was classified as SPOTTING.
Time frame: Up to 1 year
Participants kept diaries to record vaginal bleeding events. They were asked to record, on a daily basis, whether vaginal bleeding was present. Absence of withdrawal bleeding was defined as no bleeding/spotting during the expected bleeding period.
