Supplementary Figure S2 from Minimal Residual Disease Enhances Prognostic Stratification beyond Pathologic Response in Resectable Non–Small Cell Lung Cancer

Supplementary Figure 2. Kaplan–Meier curves for event-free survival (EFS) and overall survival (OS) according to minimal residual disease (MRD) status. (A) EFS in the experimental arm. (B) OS in the experimental arm. (C) EFS in the control arm. (D) OS in the control arm. MRD positivity was defined as MRD detection at any time point. Hazard ratios (HR) with 95% confidence intervals were estimated using Cox proportional hazards models, and P values were calculated with the log-rank test.
