If not normally distributed, they were expressed as median and interquartile range [M(Q1, Q3)] and analyzed using the Mann-Whitney U test. Categorical data were represented as percentages (%) and analyzed using the chi-square test or Fisher’s exact test for low incidence rates. A p-...

Chi-square test and logistic regression were used to determine associations between HIV status and PCa. RESULTS: Total of 8000 black men were included, mean age 67.5 years (range 45-90), PSA (ng/ml) median=62 (range 9-100), HIV-(n=6000) vs HIV+(n=2000), HIV-(PCa: n=4860,81%...
