Differential analysis of intestinal microbiota and metabolites in mice with dextran sulfate sodium-induced colitis

Table 1 Disease activity index assessment standards

Score	Weight loss rate	Stool consistency	Fecal occult blood
0	< 1%	Normal	Negative
1	1%-5%
2	5%-10%	Soft stool (mushy)	Positive
3	10%-15%
4	> 15%	Watery stools (mostly near the anus)	Visible bloody stools or hematochezia

Weight loss rate = (weight the day before the material is taken - weight 2 d before the material is taken)/the weight of the day before the material is taken × 100%.
