Multivariable logistic regression and adjusted odds ratio for the incidence of urinary incontinence after RP a
| Parameter | Effect estimate ± SE | p value | Odds ratio (95% CI) |
|---|---|---|---|
| Age at RP | 0.05 ± 0.01 | <0.0001 | 1.05 (1.03–1.06) |
| Lymph node dissection | 0.28 ± 0.09 | 0.003 | 1.34 (1.12–1.61) |
| Radiotherapy b | 0.26 ± 0.17 | 0.91 | 1.294 (0.921–1.81) |
| HV1-HV2 vs LV1-LV2 | −0.36 ± 0.06 | <0.0001 | 0.48 (0.38–0.62) |
| LV1-HV2 vs LV1-LV2 | 0.01 ± 0.07 | 0.88 | 0.71 (0.55–0.92) |
| Intercept | −3.85 ± 0.53 | <0.0001 |
CI = confidence interval; HV = high RP volume; HV1 = HV during 2016–2018; HV2 = HV during 2019–2020; LV = low RP volume; LV1 = LV during 2016–2018; LV2 = LV during 2019–2020; RP = radical prostatectomy; SE = standard error.
a
For the final model, total concordance was 61.3%, with χ2 = 8.20 (Hosmer and Lemeshow test; p = 0.42).
b
Not included in the final model.
