The Nara Declaration 2023 recommends that patients with ALT levels of >30 U/L and those who have steatosis, diabetes, hypertension, and/or dyslipidemia should be referred to a hepatologist, considering the results of the FIB4 index and/or platelet count. ALT levels of >30 U/L is a simple and useful indicator and, when combined with the FIB4 index and platelet count, can detect MASLD cases that require further treatment and follow-up. Moreover, among patients with MAFLD and ALT levels of ≤30 U/L, the FIB4 index may be useful for identifying those at risk of MASLD. The Nara Declaration 2023 is an important and convenient guideline that provides primary care doctors with specific indications for referral to a hepatologist. When combined with the FIB4 index, ALT levels of >30 U/L is expected to predict high-risk MASLD cases.
