The authors compared definitions of potency according to the International Index of Erectile Function 5-item short version (IIEF-5) and the Expanded Prostate Cancer Index Composite (EPIC) and observed that IIEF-5 and EPIC scores were highly correlated but that potency rates varied widely, depending on the definition of potency used. The current results may help with the interpretation of sexual function outcomes data in patients with prostate cancer.
