Population: ITT group consisted of all participants who were treated. n=number of participants with non-missing values at the respective time point.

The Insler Score was assessed on Day 6 after ovulation during the Screening Cycle, on Day 21 of Cycle 1, and when the maximum follicle diameter was greater than or equal to 15 mm. The Insler Score consisted of four categories each scaled from 0 (none) to 3 (complete). The higher the score, the greater the cervical reaction.

SECONDARY outcome

Timeframe: 6 cycles

Population: The "restricted ITT" set included all participants treated and excluded nonpregnant participants who didn't have \>=1 cycle expected to be at risk for pregnancy (with recorded use of condoms or without sexual intercourse per diary card data).

In-treatment pregnancies were pregnancies with an estimated date of conception from the day of first intake of trial medication up to and including the day of last (active or placebo) intake of trial medication extended with a maximum of two days. Each 13 cycles (28 days per cycle) of exposure constitutes a woman year. The Pearl Index was obtained by dividing the number of in-treatment pregnancies that occurred by the time (in 100 woman years) that the women were under risk of becoming pregnant.

SECONDARY outcome

Timeframe: Every 28-day cycle for 6 cycles

Population: The ITT group consisted of all participants who were treated; ITT analyses of vaginal bleeding patterns were based on all participants in the ITT group who had at least one evaluable cycle. Cycles were considered to be non-evaluable in case of insufficient bleeding data or improper cycle length. n=number of participants with evaluable cycles.

Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary card booklets. Participants documented whether vaginal bleeding was present, and if present, indicated whether it was considered to be spotting or bleeding. Breakthrough bleeding/spotting was defined as any episode that occurred during the "expected non-bleeding period" that was neither an early nor a continued withdrawal bleeding. Expected non-bleeding period: DRSP-EE group: 21-day period starting on Day 1 of the cycle; NOMAC-E2: 21-day period starting on Day 4 of the cycle.

Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary card booklets. Participants documented whether vaginal bleeding was present, and if present, indicated whether it was considered to be spotting or bleeding. Continued withdrawal bleeding was defined as any withdrawal bleeding that continued into the "expected non-bleeding period" of the next cycle. Expected non-bleeding period: DRSP-EE group: 21-day period starting on Day 1 of the cycle; NOMAC-E2: 21-day period starting on Day 4 of the cycle.

SECONDARY outcome

Timeframe: Every 28-day cycle for 6 cycles

Population: ITT analyses of vaginal bleeding patterns were based on all participants in the ITT group who had at least one evaluable cycle. Cycles were considered to be non-evaluable in case of insufficient bleeding data or improper cycle length. n= number of participants who had breakthrough bleeding/spotting for the respective cycle.

Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary card booklets. Participants documented whether vaginal bleeding was present, and if present, indicated whether it was considered to be spotting or bleeding. Breakthrough bleeding/spotting was defined as any episode that occurred during the "expected non-bleeding period" that was neither an early nor a continued withdrawal bleeding. Expected non-bleeding period: DRSP-EE group: 21-day period starting on Day 1 of the cycle; NOMAC-E2: 21-day period starting on Day 4 of the cycle.
