We further analyzed the predictive diagnostic value of the different noninvasive indicators for different stages of liver fibrosis, and the AUROC for APRI was 0.63 for significant fibrosis and 0.68 for advanced fibrosis, which were higher than those for FIB-4 (0.60 for significant fibrosis / 0.67 for advanced fibrosis) and AST/ALT ratio (0.52 for both significant and advanced fibrosis). Here, GPT is linked to Hepatic fibrosis.
