CI—confidence interval; coeff—beta coefficient; PSA—prostate-specific antigen; ref—reference group for categorical/binary variables

Note. Intercept represents referent participant, a 63.5-year-old, non-Hispanic White, married, gay man who had surgery and is 5.8 years since diagnosis, with a PSA level at diagnosis of 7.6 ng/ml and high social support.
