Criteria used for histological scoring

Score	Steatosis	Lobular inflammation	Portal inflammation intensity	Portal inflammation extent
0	<5% of lobular parenchyma	No inflammation	Nil	No
1	<25% of lobular parenchyma	Sparse zone 3 inflammation	Mild	<25% of portal tracts
2	<50% of lobular parenchyma	Mild focal zone 3 inflammation	Moderate	<50% of portal tracts
3	<75% of lobular parenchyma	Notable zone 3 inflammation	Severe	<75% of portal tracts
4	>75% of lobular parenchyma	Severe zone 3 inflammation		>75% of portal tracts
