Multivariable-adjusted regression model. Covariates: age (continuous), race (black, white), marital (married/living with partner, single/divorced/widowed), education (≤ high school, ≥ some college), income (<$60,000, $60,000 - <100,000, ≥$100,000, Unknown), body mass index (<25, 25 - <30, ≥30 kg/m2), cancer stage (0, I, II, III/IV, unknown), comorbidities (1, >1, unknown), Time since AET initiation (≤6months, >6 months, unknown), Time since diagnosis (≤1 year, >1 year, unknown), tangible support (score ≤15, 16–19, >19), emotional/informational support (score ≤31, 32–39, >39).
