Cedrol ameliorates ulcerative colitis via myeloid differentiation factor 2-mediated inflammation suppression, with barrier restoration and microbiota modulation

Table 2 Histopathological scoring criteria

Score	Inflammation extent	Crypt damage	Ulceration	Edema
0	None	Intact crypt architecture	No ulcer	Absent
1	Scattered submucosal cells	Some crypt damage	Small focal ulcers	Present
2	Focal submucosal infiltrates	Increased crypt spacing, goblet cell loss, crypt shortening	Frequent small ulcers
3	Focal submucosal, lamina propria infiltrates	Large crypt-deficient areas amid normal crypts	Extensive surface epithelial loss
4	Extensive submucosal, lamina propria, perivascular infiltrates	Crypt absence
5	Transmural inflammation
