Data are shown only for statistically significantly different characteristics. PORPUS-P: Patient-Oriented Prostate Utility Scale-Psychometric; PSA: prostate-specific antigen; CCS: Charlson comorbidity score; SD: standard deviation; RARP: robot-assisted radical prostatectomy; ORP: open radical prostatectomy.
All Charlson comorbidities are not captured in the PCDB. The following are captured: myocardial infarction, congestive heart failure, peripheral vascular disease, liver disease, diabetes mellitus, leukemia, lymphoma, AIDS, cerebrovascular Disease, dementia, pulmonary disease, rheumatologic disease, and peptic ulcer.
Missing biopsy Gleason scores: n = 35 ORP, n = 17 RARP.
Missing ethnicity: n = 340 ORP, n = 175 RARP.
