BZA 20 mg/CE 0.45 mgDrug
There was no drug taken during study 3115A1-4000. During the 3115A1-303 study the test article was supplied as baxedoxifene/CE tablets in capsules. Subjects took one capsule orally, once daily at approximately the same time each day on a continuous regimen for 2 years or until early termination from the study.
BZA 20 mg/CE 0.625 mgDrug
There was no drug taken during study 3115A1-4000. During the 3115A1-303 study the test article was supplied as baxedoxifene/CE tablets in capsules. Subjects took one capsule orally, once daily at approximately the same time each day on a continuous regimen for 2 years or until early termination from the study.
Raloxifene 60 mgDrug
There was no drug taken during study 3115A1-4000. During the 3115A1-303 study the test article was supplied as raloxifene tablets in capsules. Subjects took one capsule orally, once daily at approximately the same time each day on a continuous regimen for 2 years or until early termination from the study.
PlaceboDrug
There was no drug taken during study 3115A1-4000. During the 3115A1-303 study the test article was supplied as placebo capsules. Subjects took one capsule orally, once daily at approximately the same time each day on a continuous regimen for 2 years or until early termination from the study.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percent Change From Baseline in Mammographic Breast Density at Month 24
The digitized mammogram pairs were analyzed by a single trained radiologist who determined the density of the breast using software. The only left craniocaudal view was used for assessing breast density.
Measured: primary study baseline, Month 24
