Kleiner 2005 NAFLD activity score (NAS)
Kleiner 2005 NAFLD activity score (NAS): caller-assigned steatosis 0-3 (<5% / 5–33% / >33–66% / >66%), lobular_inflammation 0-3 (none / <2 foci per 200× / 2–4 / >4), ballooning 0-2 (none / few / many or prominent). magent sums only (max 8). Fibrosis is not in NAS. Kleiner 2005 reported NAS ≥5 correlated with NASH in that study; that is not a diagnostic algorithm. magent does not read histology and does not return NASH bands.
