This article offers best practice advice -here are two of them:

#2: A Fibrosis 4 Index score <1.3 is associated with strong negative predictive value for advanced hepatic fibrosis and may be useful for exclusion of advanced hepatic fibrosis in patients with NAFLD.

#8 Patients with NAFLD and NITs (noninvasive tests) results suggestive of advanced fibrosis (F3) or cirrhosis (F4) should be considered for surveillance of liver complications (eg, hepatocellular carcinoma screening and variceal screening per Baveno criteria). Patients with NAFLD and NITs suggestive of advanced hepatic fibrosis (F3) or (F4), should be monitored with serial liver stiffness measurement; vibration controlled transient elastography; or magnetic resonance elastography, given its correlation with clinically significant portal hypertension and clinical decompensation.

In this study from U.S., patients (n=2523) were divided into three categories based on FIB-4 scores: (A) Fibrosis-4 (FIB-4) <1.3 and/or liver-stiffness measurement (LSM) measured by Fibroscan <8 kp, (B) FIB-4 1.31‒2.6 and/or LSM 8.1-12.5 kp, and (C) FIB-4 >2.6 and/or LSM >12.5 kp. However, those in class A with aspartate transaminase:alanine transaminase ratio >1 or platelets <150,000/mm³, or class B with aspartate transaminase:alanine transaminase ratio >1 or platelets <150,000/mm³ were upstaged by one class. The data were reviewed retrospectively from a prospective longitudinal cohort (TARGET-NASH)

Key findings: All adverse outcomes including liver and cardiovascular (see below) were correlated with FIB-4 staging.

S Man et al. Gastroenterol 2023; 165: 1025-1040. Open Access! Prevalence of Liver Steatosis and Fibrosis in the General Population and Various High-Risk Populations: A Nationwide Study With 5.7 Million Adults in China

Key findings: The prevalence of steatosis, severe steatosis, advanced fibrosis, and cirrhosis was 44.39%, 10.57%, 2.85%, and 0.87%, respectively in Chinese adults

Limitation: This data was derived from a health checkup cohort which could give different results than a random population sampling. Patients at health checkups may be more health conscious and/or be aware of underlying health concerns.

My take: Steatotic liver disease is a huge worldwide problem. The growing prevalence is going to result in extensive health issues.
