Cox proportional hazards model to assess the risk of postoperative Peyronie’s disease
| Variable | Hazard ratio | 95% Confidence interval | p value | |
|---|---|---|---|---|
| Time from surgery | 0.99 | 0.98 | 1.01 | 0.626 |
| RS-RARP vs S-RARP | 0.98 | 0.47 | 2.03 | 0.947 |
| Nerve sparing | 0.95 | 0.51 | 1.74 | 0.856 |
| Preoperative EPIC sexual domain score | 0.99 | 0.93 | 1.06 | 0.823 |
| Postoperative potency | 1.04 | 0.81 | 1.32 | 0.780 |
EPIC = Expanded Prostate Cancer Index; RS-RARP = Retzius-sparing robotic-assisted radical prostatectomy; S-RARP = standard robotic-assisted radical prostatectomy.
