From: Interleukin-37 is increased in ankylosing spondylitis patients and associated with disease activity
Associations between serum levels of IL-37 and pro-inflammatory cytokines in AS patients. Serum IL-37 levels were positively correlated with IL-6 (A), IL-17 (B), TNF (C) respectively except for IL-23 (D). Each symbol represents an individual patient. The correlations were evaluated with Spearman’s non-parametric test. P < 0.05 represents a significant difference. NS, not significant.
