Note. ADT+ = prostate cancer patients treated with ADT; ADT− = prostate cancer patients not treated with ADT; CA− = men with no history of prostate cancer; SD = standard deviation. p values calculated using t-tests for continuous variables and χ2 tests or Fisher’s exact tests for categorical variables. Missing values were excluded from analyses. In analyses with cell sizes ≤ 5, p values were calculated using Fisher’s exact test which yields no test statistic.
