Fibrosis Progression in NASH

Approximately 40% of NASH patients progress to fibrosis globally (1,2)

  • 5% and 10% of patients with NASH diagnosed on their initial biopsy will present with clinically significant fibrosis at this initial biopsy, and an additional 15-20% will progress to advanced fibrosis in less than a decade (2)
  • age and presence of inflammation on initial biopsy are independent predictors of progression to advanced fibrosis (3)
