Fig. 2From: TP53 mutation prevalence in normal airway epithelium as a biomarker for lung cancer riskROC curves with AUC (95% confidence limits) for a CBM comprising the PLCOM2012 Risk Score (PRS) + TP53, b PRS alone, and c TP53 biomarker alone. The AUC for the CBM was significantly higher (P = 0.03) compared to PRS or TP53 aloneBack to article page
