Assessment of Inflammation by Means of Clinical and Macroscopic Score

Scorea	Diarrhea score	Visible fecal blood	Inflammatory score
0	Normal pellets	Normal	Normal
1	Slightly loose feces	Slightly bloody	Slight inflammation
2	Loose feces	Bloody	Moderate inflammation and/or edema
3	Watery diarrhea	Blood in whole colon	Heavy inflammation and/or ulcerations and/or edema

^aScore reflects degree of diarrhea, visible fecal blood, and inflammatory score on the day of termination and is characterized on a scale of 0–3. Inflammatory score reflects macroscopical appearance of the colon (inflammatory score) judged by degree of inflammation and presence of ulcerations and/or edema in the tissue.
