Relationship between serum IL-21 and IgG levels at onset and remission in patients with AIH. a Comparison between AIH patients at onset of acute (n = 11) or chronic (n = 11) presentation. b Relationship between serum IL-21 levels and serum IgG levels in patients with AIH at onset of acute AIH. c Relationship between serum IL-21 levels and serum IgG levels in patients with AIH at onset of chronic AIH. d Comparison between AIH patients at onset and remission (n = 8). e Relationship between serum IL-21 levels and serum IgG levels in patients with AIH at remission. p values were calculated with the Mann–Whitney test, Spearman rank correlation test, or Wilcoxon matched-pairs signed-rank test, ns not significant
