PSM, propensity score matching; n, number of cases/controls; RT, radiotherapy; OS, overall survival; CSS, cancer‐specific survival; CI, confidence interval; AD, adenocarcinoma; SQC, squamous cell carcinoma; Other, other specified carcinoma; LCC, large cell carcinoma; Unspecified, unspecified malignant neoplasm; NSCLC, non‐small cell lung cancer.
PSM were done in each subgroup using variables including: age, gender, race, marital, grade, T stage, N stage, chemotherapy, surgery, radiotherapy, and metastatic sites of bone, brain, liver, and lung.
Derived from Kaplan‐Meier survival analysis.
