Enterocolitis score system for histology evaluation

Numerical score	Intestinal-fold architecture disruption			Goblet cell appearance
	Impaired epithelial integrity	Expanded clefts/reduced projections	Expanded gut lumen
0	Normal	Normal	Normal	Normal
1	Slight disruption	Slight disruption	Slight expansion	Increased in number
2	Moderate disruption	Moderate disruption	Moderate expansion	Increased in number and different in sizes
3	Severe disruption	Severe disruption	Severe expansion	Severe morphological changes
