This retrospective multicentre cohort study will use existing medical records from adults with Metabolic Dysfunction-Associated Steatotic Liver Disease or Metabolic Dysfunction-Associated Steatohepatitis (MASLD/MASH) who underwent two Vibration-Controlled Transient Elastography-Liver Stiffness Measurement (VCTE-LSM) (FibroScan) assessments during routine clinical care. The study will evaluate whether changes in fibrosis risk tier between the two assessments are associated with future major liver-related outcomes and all-cause mortality. The duration of study will be 5 months.
