Impact of triglyceride-glucose index on the long-term prognosis of advanced gastric cancer patients receiving immunotherapy combined with chemotherapy

Figure 1 Flow chart depicting the screening of gastric cancer patients who received sintilimab combined with chemotherapy. PD-1: Programmed cell death protein 1; PD-L1: Programmed cell death ligand 1; TyG: Triglyceride glucose.

Figure 2 Effects of different triglyceride glucose indexes on the long-term prognosis of gastric cancer patients. A: Kaplan-Meier plot of the triglyceride glucose (TyG) index < 1.79 and TyG index ≥ 1.79 groups; B: Kaplan-Meier plot of overall survival in the TyG index < 1.79 and TyG index ≥ 1.79 groups. TyG: Triglyceride glucose; HR: Hazard ratio; CI: Confidence interval.
