    • Originally derived in a Northern Italian cohort but has since been validated in multiple cohorts including North America, China, and the UK.
    • May help in patient selection for ultrasound or liver biopsy.
    • Validated in multiple external cohorts.
    • May be used in the research setting to identify patients for planning observational or interventional studies.
