Fig. 2From: Preoperative serum immunoglobulin G and A antibodies to Porphyromonas gingivalis are potential serum biomarkers for the diagnosis and prognosis of esophageal squamous cell carcinomaReceiver 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)Back to article page
