Overall survival (OS) and lung cancer-specific survival (LCSS) in patients with different age ranges according to the use of postoperative radiation therapy (PORT) after propensity score-matching (PSM). a, OS curves for patients aged <60 years. The 5-year OS rate was 35.4% for the PORT group and 28.9% for the no PORT group. b, LCSS curves forpatients aged <60 years. The 5-year LCSS rate was 39.5% for the PORT group and 36.2% for the no PORT group. c, OS curves for patients aged 60–79 years. The 5-year OS rate was 42.8% for the PORT group and 36.9% for the no PORT group. d, LCSS curves for patients aged 60–79 years. The 5-year LCSS rate was 48.2% for the PORT group and 45.0% for the no PORT group. e, OS curves for patients aged ≥80 years. The 5-year OS rate was 47.9% for the PORT group and 29.2% for the no PORT group. f, LCSS curves for patients aged ≥80 years. The 5-year LCSS rate was 49.0% for the PORT group and 33.3% for the no PORT group
