PKM and neoplasm: Further logistic regression models and ROC curve analyses, interestingly, revealed that the T stage-O-GlcNAc-PKM2 triple model exhibited the best performance (Table S7, AUC = 0.722) when compared with the invasive tumor size-O-GlcNAc-PKM2 model (AUC = 0.699) and the CTS5-O-GlcNAc-PKM2 model (AUC = 0.712).
