Adjusted for each of the following, exclusive of the variable of being compared: participant SES (high vs. low), age (≥65 vs. less than 65), race (White vs. Black vs. other), surgery choice (breast‐conserving surgery vs. mastectomy), cancer stage (I vs. II vs. III), and study site as fixed effects and surgeon and clinic as random effects.
