Criteria for scoring the DAI⁽¹⁾.

Score	Weight loss (%)	Stool consistency^(2)	Bloodstain or; gross bleeding

1	1–5	Loose stool	Negative
2	5–10	Loose stool	Positive
3	10–15	Diarrhea	Positive
4	>15	Diarrhea	Gross bleeding

⁽¹⁾Disease activity index = (combined score of weight loss, stool constancy, and bleeding)/3. ⁽²⁾Normal stool = well-formed pellets; loose stool = pasty stool that did not stick to the anus; and diarrhea = liquid stool that stuck to the anus.
