The results of ROC analysis on the potential protein biomarker ranges identified by MALDI-ToF from gargle samples. Panel 6A-G present the graphs of true versus false positive rate for each of the seven labeled m/z ranges. In any given panel, each point represents a MALDI-ToF specificity/sensitivity value at a cutoff AUC for each potential biomarker range, with the highest specificity/sensitivity and discriminating power having values near the top left of each plot.
