Fig. 2

Macroscopic score of colonic damage. NC normal control group, MC model control group, MESA mesalazine group, and HPM herb-partitioned moxibustion group. ★P < 0.001 versus NC, ★★P < 0.05 versus NC; △P < 0.001 versus MC. The data of macroscopical score do not have normal distribution, the box-plot is used to express, as shown below. The NC group has the same value, so the box-plot only have one straight line. The maximum value is equal to the upper quantile and the minimum value is equal to the lower quantile in MC group. The maximum value is equal to the upper quantile in MESA group. The maximum value is equal to the upper quantile and the minimum value is equal to the lower quantile in HPM group
