Risk Group | Prognostic Score | Patients n (%) | Mean time to recurrence (months) |
---|---|---|---|

The prognostic score was calculated as follows: eGFR (60–20 ml/min) × 0.56/1.199 + eGFR (<20 ml/min) × 1.199 /1.199 + Current-Smoker × 1.128/1.199 + Heavy-areca nut chewing × 0.778/1.199 + Grade-high × 0.663/1.199.
