KRT18 and metabolic dysfunction-associated steatotic liver disease: Although the NAFLD Fibrosis Score is based on readily-available variables that are typically collected as part of the routine check-up for NAFLD patients, elastographic imaging modalities for liver stiffness have an inherent advantage in terms of immediacy over more complex biomarker assays such as ELF and CK-18, as elastography does not require the time-consuming blood sampling and laboratory processing.
