^a:

adjusted for age, sex, race

^b:

adjusted for sex, race, age, education, categories of number of comorbidities, marital status, PCS score (tertiles), year of diagnosis, smoking status

^c:

Number of events for fully adjusted model was lower than crude and minimally adjusted models due to missing values in covariates included for adjustment.
