Class-specific (A) and stage-specific (B) survival curves with 95% confidence intervals and risk tables. A The index classification using an inverse of treatment decision function was applied to NSCLC cancer patients in Korean National Health Insurance database (N = 71,593), and class-specific survival function was estimated with the non-parametric Kaplan–Meier method. B The cancer stages (TNM 7th edition) were inferred from the index classification, and stage-specific survival function was estimated with the non-parametric Kaplan–Meier method. Stage I and IIA are aggregated in the survival curve because the index classification cannot distinguish them
