A. VeriStrat as a prognostic marker among patients who had active supportive care only, according to ECOG and age: Overall survival for VeriStrat Good (solid line) and Poor (dashed line). Hazard ratios (HRs) for VeriStrat Good vs. Poor are shown (adjusted for age, sex, ECOG, stage, histology and smoking, excluding the factor of interest). The HRs in square brackets are when EGFR-positives are excluded. Fig. 2B.
