All patients were performance status score 0–1 and treated by intensity‐modulated radiotherapy. BMI, body mass index; CCRT, concurrent chemoradiotherapy; IGRT, image‐guided radiotherapy; IMRT, intensity‐modulated radiotherapy; PET, positron emission tomography; PSW, propensity‐score weighting; RT, radiotherapy; SCLC, small cell lung cancer; sd, standard deviation.
Modified Carlson comorbidity score ≥ 1.
