Fig. 3: Survival curves and objective response rate (ORR) predicting model.

Kaplan-Meier estimates of overall survival (A), progression-free survival (B), and larynx preservation rate (C) of 51 patients with LA HSCC. Larynx preservation rate of 50 patients with T3 stage and T4 stage (D) and patients with esophagus involvement and without esophagus involvement (E). F Multivariable model predicting ORR of induction chemoimmunotherapy of patients with LA HSCC based on pre-treatment tumor diameter (cutoff value with 37.5 mm; OR = 10.2, 95%CI [1.2–100.5]), T stage (OR = 14.4, 95% [1.6–126.4]) and esophagus involvement (OR = 5.6, 95%CI [1.2–26.5]) (n = 51 cases), and receiver operating characteristic curve illustrating the discrimination ability of this model.
