The endpoints are related to frequency, amount and objective component of urinary incontinence, as reported in ICIQ-SF. Significant values accepted for inclusion in subsequent multivariable analyses (p <0.2) are in bold. BMI, body mass index; RP, radical prostatectomy; RT, radiotherapy; ADT, androgen deprivation therapy; CAB, combined androgen blockade; EPQ-R, eysenck personality questionnaire revised; ICIQ-SF, International Consultation On Incontinence Modular Questionnaire Short Form.
