Measure Type Secondary
Measure Title Number of Participants With an Occurrence of Continued Withdrawal Bleeding
Measure Description Cycle control was evaluated on the basis of vaginal bleeding pattern as recorded daily by participants using diary 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: NOMAC-E2: 21-day period starting on Day 4 of the cycle; LNG-EE: 21-day period starting on Day 1 of the cycle.
Time Frame Every 28-day cycle for 5 cycles  
Safety Issue No  

Population Description
Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate.
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.
