CI=confidence interval; HR=hazards ratio; PSA=prostate-specific antigen.

Model includes marital history (married, divorced, widowed, never married), age, race, comorbidity, log-transformed PSA, Biopsy Gleason grade

Model includes marital status (married vs. not married), age, race, comorbidity, log-transformed PSA, Biopsy Gleason grade

Marital status (binary) and marital history were analyzed in separate models.
