Study Arms:
- Transdermal Estradiol (Type: EXPERIMENTAL): Women wear a skin patch that is changed weekly and take opaque capsules by mouth daily. The capsules for women in this arm do not contain any active ingredients. The skin patch contains transdermal estradiol ranging in dose from 50 to 200 mcg/day
- Sertraline (Type: ACTIVE_COMPARATOR): Women wear a skin patch that is changed weekly and take opaque capsules by mouth daily. The skin patch contains no active ingredients, though packaging is designed to match active patches. The capsules contain sertraline ranging in dose from 25 to 200mg/day
- Placebo (Type: PLACEBO_COMPARATOR): Women wear a skin patch that is changed weekly and take opaque capsules by mouth daily. The capsules for women in this arm do not contain any active ingredients. The skin patch contains no active ingredients, though packaging is designed to match active patches.
