Core Tip

Core Tip: Non-invasive assessment of liver injury in chronic hepatitis B is evolving beyond static fibrosis markers toward biologically driven models. The L59-based nomogram proposed by Dai et al captures active fibrogenesis through transforming growth factor-βactivation, integrating molecular, inflammatory, and hematologic parameters. This approach is particularly relevant in patients with concurrent metabolic dysfunction-associated steatotic liver disease, where steatosis may be deceptively mild despite advanced fibrosis. A dual, non-invasive evaluation of fibrosis and steatosis is therefore essential to avoid underestimation of disease severity and to optimize risk stratification in dual-etiology liver disease.
