^aAll linear regression models were adjusted for the following covariates: age, gender (ref: male), race (ref: other), marital status (ref: non-married), education (ref:<Bachelor’s), employment (ref: non-employed), income (ref: ≥$50,001), private insurance (ref: no), social economic composite score (ref: teritle 1), RUCC (ref: <4), cancer site (ref: other), currently being treated (ref: yes), total comorbidities score, Global distress score, and PPCQ (ref: non-high). Significant associations (p≤0.05) are marked in bold. Marginal associations (p≤0.10) are italicized.
