Machine learning model using immune indicators to predict outcomes in early liver cancer

Figure 4 Kaplan-Meier curve analysis showing the efficacy of artificial neural networks levels as a predictor of 5-year mortality in patients with Barcelona Clinic Liver Cancer 0-A hepatocellular carcinoma after surgical resection across training and validation sets, different age groups, etiologies, and alpha-fetoprotein levels in the entire cohort. A: Kaplan-Meier survival curves for the training cohort; B: Validation cohort; C: Age < 60 years; D: Age ≥ 60 years; E: Patients with hepatitis B virus (HBV) infection; F: Patients without HBV infection; G: Alpha-fetoprotein (AFP) < 400 ng/mL; H: AFP ≥ 400 ng/mL. P values were obtained using the log-rank test. AFP: Alpha-fetoprotein; HBV: Hepatitis B virus.
