There was one question on obstructive voiding symptoms: “Do you have voiding symptoms in terms of weak stream or difficulty emptying the bladder?” The answers were ranked on an ordinal scale from 1 to 3, i.e. 1 = no symptoms, 2 = minor/moderate symptoms and 3 = major/severe symptoms. Data were dichotomized so that men who answered “2” or “3” were regarded as having voiding symptoms while those who answered “1” were regarded as being asymptomatic. Biopsy findings were classified as “cancer” or “benign outcome”.
