AI-derived continuous fibrosis stage was significantly correlated with liver stiffness by FibroScan (τ: 0.33, P < 0.001), Fibrosis-4 (τ: 0.23, P < 0.001), enhanced liver fibrosis test (τ: 0.22, P < 0.001), tissue inhibitor of metalloproteinases 1 (τ: 0.11, P = 0.02) and amino terminal propeptide of type III procollagen (τ: 0.14, P < 0.01); continuous steatosis grade was not significantly correlated with the same NIT measures. The gene discussed is TIMP1; the disease is fibrosis.
