Nomogram predicts survival probability in ESCC patients. (a) Nomogram based on clinicopathological features (age, N stage, and TNM stage) and PIS predicts 2-, 3-, and 5-year survivals in ESCC patients. Nomogram evaluated by calibration curves of (b) 2 years, (c) 3 years, and (d) 5 years. The grey lines represent an ideal evaluation, whereas the blue lines represent the performance of the nomogram. PIS: prognostic immune score; OS: overall survival.
