Mortality risk in smokers for gene expression differentiating current from never smokers (C/N) in lung tumor and non-tumor tissue samples (p<0.01)

aRelative Risk of death. Analysis based on 54 current and former smokers using 262 probes from the Current/Never smoking comparisons (98 down- and 64 up-regulated probes from T and 75 down- and 28 up-regulated probes from NT, minus 3 overlapping probes in T and NT); models adjusted for tumor stage, sex, and smoking statusb95% Confidence IntervalcT = Lung adenocarcinoma samples of any stage (N = 42); NT = Non-Tumor tissue samples (N = 34)
