Response ratios of patients with high IgG in different treatment groups.

High levels of IgG	Response well	Response poor	P value
Group A (n = 55)	29	26
Group B (n = 12)	8	4	.379
Group C (n = 12)	7	5	.724

Compared with group A, group B and group C did not show significant differences for the response rate in the patients with high IgG level.

Group A = ursodeoxycholic acid monotherapy group, Group B = dual-combination therapy group, Group C = triple-combination therapy group, IgG = immunoglobulin G.
