Measure Description |
Time Frame |
|---|---|---|
|
Pearl Index
Time Frame: Up to 3 years
|
The Pearl Index (PI) is defined as the number of pregnancies per 100 woman years.
The 3-year PI was obtained by dividing the number of pregnancies that occurred during the first three years of treatment by the time (in 100 women years) that the women were under risk of getting pregnant.
