Values are mean ± SD (n) or n (%). PSA, prostate-specific antigen; BMI, body mass index. Prostate cancer must be T1 or T2 based on the American Joint Committee (7th edition) to meet study inclusion criteria. RUCA codes are based on 2010 Rural-Urban Commuting Area Codes – 1, Metropolitan area core: primary flow within an urbanized area (UA); 2, Metropolitan area high commuting: primary flow 30% or more to a UA; 3, Metropolitan area low commuting: primary flow 10% to 30% to a UA; 4, Micropolitan area core: primary flow within an Urban Cluster of 10,000 to 49,999 (large UC); 5, Micropolitan high commuting: primary flow 30% or more to a large UC.
