*Adjusted costs employed regression models (generalized linear model with gamma distribution and logarithmic link) to control for baseline differences between women receiving each treatment. The regression included the following control variables, all measured on the index date or during the 1 year baseline period: age, region, type of health plan, year of procedure, whether the patient was an employee or dependent, whether or not the employee was active full-time, whether the employee was salaried, demographics characteristics of the ZIP Code where the patient lived, indicators for any outpatient prescription drug fills of hormone therapies and NSAIDs, the Deyo Charlson Comorbidity Index, number of psychiatric diagnostic groupings, indicators for comorbidities, and indicators for any hospital stays and any emergency department visits during the baseline year. Demographics of the ZIP code included quintile of zip code median family income, quintile of percent black and quintile of percent with a college degree.
