Caffeic acid phenethyl ester inhibits liver fibrosis in rats

Table 1 Degree of liver fibrosis in the groups (n = 6 for each group)

Group	0	1	2	3	4
Normal	6	0	0	0	0
Vehicle	6	0	0	0	0
Model	0	0	0	3	3
Vit E	0	4	2	0	0
CAPE (mg/kg)
3	0	0	2	3	1
6	0	1	3	2	0
12	0	5	1	0	0

H = 46.12. Model group vs normal group, χ² = 9.778, P < 0.05; Vitamin E (Vit E) group vs model group, χ² = 8.899, P < 0.05; Caffeic acid phenethyl ester (CAPE; 12 mg/kg) vs model group, χ² = 9.209, P < 0.05. The results were statistically analyzed by the nonparametric Kruskal-Wallis H test followed by Wilcoxon test for paired comparisons.
