| Characteristic | Coefficient (min) | 95% CI | P value |
|---|---|---|---|
| History of UTI | 24.23 | 2.48–45.97 | .023 |
| History of antiplatelet agents | 19.51 | − 3.16 to 42.19 | .021 |
| HoLEP specimen weight | |||
| < 15 g | Reference | ||
| 15–50 g | 17.28 | 1.01–33.56 | .024 |
| 50–80 g | 36.37 | 8.33–64.4 | .012 |

Other abbreviations as in Table 1. Interpretation of linear regression model: for a patient with a history of UTI and antiplatelet agents, who had a HoLEP specimen weight of 35 g, the estimated enucleation time is 79.36 min (24.23 + 19.51 + 17.28 + 18.34 = 79.36)
