Relationship between serum IL-21 and histology. Serum IL-21 levels according to the degree of necroinflammatory activity and liver fibrosis. a Grading of necroinflammatory activity, b staging of fibrosis. Although serum IL-21 levels did not correlate with staging of fibrosis (r = 0.45, p = 0.056), they were significantly positively correlated with grading of necroinflammatory activity (r = 0.68, p < 0.005). p values were calculated with Spearman rank correlation test
