Intriguingly, GGT was replaced with ALT and AST in the formula of 1000×ALT/(PLT×albumin2) and 1000×AST/(PLT×albumin2), which revealed that the AUC value of predicting oesophageal varices was 0.681 and 0.663, respectively, and that the AUC value of predicting severe oesophageal varices was 0.718 and 0.701, respectively. Here, GPT is linked to esophageal varices.
