aOf the 481 non-squamous patients, two were missing ECOG PS.
bTwo-sample t-test. Bold P-values are significant.
cASBI = mean of six LCSS items: loss of appetite, fatigue, cough, dyspnea, pain, and hemoptysis.
LCSS, lung cancer symptom scale; PS, performance status; QoL, quality of life; ASBI, average symptom burden index.
