| Uric acid ≥6.8 mg/dL, yes vs no | 3.67 (2.89 to 4.64) | <0.001 |
| Hypertension, yes vs no | 1.43 (1.03 to 1.97) | 0.03 |

A total of 201 events (10%) occurred in the control group, whereas 138 events (7%) occurred in the surgery group during a follow-up for up to 26 years. The adjusted HRs were calculated using a Cox proportional hazards model based on baseline data.
