These included women with a uterus on hormone therapy (HT), both estrogen and progestin, and hysterectomized women on estrogen therapy (ET) only.CRITIQUE OF WOMEN'S HEALTH INITIATIVE STUDYExcludes patients with vasomotor symptomsPrimary indication for hormone replacementMean patient age was 63 yearsMissed the 10-year "window of opportunity"Same dose of hormone for all agesOlder women don't need as a high dose as do younger womenPatients were not all healthyHypertension (40%), t cholesterol (15%), diabetes mellitus (7%), myocardial infarction (3%)Benefits: Both HT and ET groups in WHI had decreased osteoporotic fractures and lower rates of colorectal cancer.Risks: Both HT and ET groups in WHI were found to have small increases in deep vein thrombosis (DVT).
