Table 2. List of selected significantly altered functions in the CO and KO groups which might be involved directly and indirectly in the progression of colitis.

The confidence interval threshold was 95% and p<0.05. Dark grey color indicates the abundance of a particular function is increasing and light grey color indicates the abundance of a particular function is decreasing.
