NFLSI = NCCN Functional Assessment of Cancer Therapy – Lung Symptom Index; DRS = disease-related symptoms; TSE = treatment-related side effects; F/WB = Functional/Well-being-related symptoms

a

Two items from NFLSI are not on FACT-L, so 15-item NLSI was used in analyses

b

Correlations adjusted for overlap not calculated-too few items remained

c

No overlap, adjusted correlations not needed
