Detailed scoring system for assessing the disease activity index (DAI).

Score	Body weight loss	Stool	Bleeding
0	None	Normal	No bleeding
1	1–5%	Soft but still formed	No bleeding
2	6–10%	Soft	Positive hemoccult
3	11–18%	Very soft or wet	Visible blood traces
4	> 18%	Watery diarrhea	Gross bleeding

DAI scores = body weight loss scores+ stool scores + bleeding scores.
