Demographics table stratified by pad use groups and analyzed by analysis of variance. Table compares the excluded 0-pad use group with the pad use group, analyzed by t test.
P values (analysis of variance) presented are for intergroup comparisons. A simple comparison is also made between men pad free within the first 7 days after catheter removal (0 pads) with all men using pads (1+ pads) using t tests.
SD=standard deviation; AUA=American Urological Association; PSA=prostate-specific antigen; BMI=body mass index; IIEF=International Index of Erectile Function; PVR=postvoid residual; PFR=peak flow rate.
