Receiver operating characteristic (ROC) curves and clinical performances of P. gingivalis IgG and IgA. a ROC curves of IgG, IgA and combination of IgG and IgA for P. gingivalis as a diagnostic marker for discrimination of ESCC and non-ESCC controls. b Clinical performances of IgG, IgA and combination of IgG and IgA for P. gingivalis as a diagnostic marker for discrimination of ESCC and non-ESCC controls in terms of accuracy, sensitivity, specificity, false negative rate (FNR), false positive rate (FPR). c Time-dependent ROC curves of IgG, IgA and combination of IgG and IgA for P. gingivalis as predictors of ESCC-related 3-year survival rates. d Clinical performances of IgG, IgA and combination of IgG and IgA for P. gingivalis predictors of ESCC-related 3-year survival rates in terms of accuracy, sensitivity, specificity, false negative rate (FNR), false positive rate (FPR)
