CI = confidence interval; ED = erectile dysfunction; IIEF = International Index of Erectile Function; SD = standard deviation.

^†Paired t test p value for continuous variables; McNemar test p value for categorical variables for change within group from baseline to month 6.

^§The p value for δ change between groups from baseline to month 6 using repeated measures ANOVA for continuous variables and the Fisher exact test for categorical variables.

^*A total IIEF score <21 indicates ED.
