Kaplan Meier curves for overall survival (A), real-world progression (B), and real-world progression-free-survival (C) of patients with advanced lung cancer treated with chemotherapy and immune checkpoint inhibitors compared to chemotherapy alone, stratified by corticosteroid use. Kaplan Meier plots represent the inverse-probability-weighted estimates. Risk tables listed below the plots include both crude (before weighting) and inverse-probability-weighted populations at each time point.
