Overall survival (OS) and lung cancer-specific survival (LCSS) according to the use of postoperative radiation therapy (PORT) before and after propensity score-matching (PSM). a, OS curves before PSM. The 5-year OS rate was 37.7% for the PORT group and 34.1% for the no PORT group. b, LCSS curves before PSM. The 5-year LCSS rate was 43.5% for the PORT group and 30.6% for the no PORT group. c, OS curves after PSM. The 5-year OS rate was 41.3% for the PORT group and 34.1% for the no PORT group. d, LCSS curves after PSM. The 5-year LCSS rate was 46.0% for the PORT group and 41.6% for the no PORT group
