(A) Scoring table and the proposed risk-stratification model. Weighted scores were given according to the coefficient value in the multivariate analysis; 1 point is given if the value of the coefficient is 0–1, 2 points if the coefficient value is 1–2 and 3 points when it is over 2. Total scores were calculated and classified into three distinctive risk groups according to the total scores (0–2: Low risk, 3–4: Intermediate risk, 5–7: High risk). (B) Kaplan–Meier survival curves in each risk groups stratified by the proposed risk-stratification model in patients with negative surgical margins after robot-assisted radical prostatectomy.
