clinical correlation analysis based on risk assessment model. (A–G) Bar graph (A) and scatter diagram show that T (B), M (C), N (D), and (E) clinical stage were associated with a significant risk score. (F) Single-variable Cox regression to prove the clinical stage (p < 0.001, HR = 2.208, 95% CI [1.722–2.831]), the risk score (p < 0.001, HR = 1.004, 95% CI [1.003–1.005]) showed statistical significance, and multivariate Cox regression analysis prove that age (G) (p < 0.001, HR = 1.035, 95% letter interval [1.015–1.056]) and the clinical stage (p < 0.001, HR = 2.260, 95% CI [1.750–2.918], HR = 1.003, 95% CI [1.002–1.005])
