^*Model 1: Adjusted for age (continuous), time between diagnosis and social support assessment (continuous), race (white (ref), black, Asian, Hispanic, other), and stage (I (ref), II, III)

^**Model 2: Adjusted additionally for chemotherapy (no (ref), yes), radiation (no (ref), yes), type of surgery (lumpectomy (ref), mastectomy, other), nodal status (positive, negative (ref), unknown), comorbidity at baseline (no (ref), yes, unknown), HER2 status (positive, negative (ref), unknown), educational status (high school or less, some college/vocational school (ref), college graduate, post-graduate) and income (<$25,000, $25,000–69,999, $70,000+ (ref), unknown). Further adjustment for alcohol use, physical activity, BMI, and smoking status did not substantively influence associations and these covariates were not included in models.

^†Model 3: Simultaneously adjusted for personal and clinical social support.
