SIR biomarkers as prognostic for NSCLC overall survival (OS)
The median follow-up for the sample was 8 months, with an inter-quartile range of 3 to 22 months and a range of 0 to 24 months. Overall mortality at 2-years was 61% (113/186). Survival analyses used the SIR cutoffs noted above and adjusted for covariates (i.e., ECOG-PS, age, educational level, smoking status, and treatment received at baseline). Analyses determined statistically significant associations between each biomarker and overall survival (
