Receiver-operator characteristic (ROC) curve analysis of abundances of bacterial genera in sputum of cohort 1 comprising NSCLC patients and cancer-free controls. The area under the ROC curve (AUC) for bacterial genera conveys its accuracy for diagnosis and classification of NSCLC. (A) The combined use of Acidovorax and Veillonella produced 0.91 AUC. (B) The use of Capnocytophaga as a sputum biomarker could detect lung AC with 0.85 AUC. (C) The use of Acidovorax as a sputum biomarker had 0.85 AUC for differentiating between SCC and SC of the lungs.
