Fig 2: CCL7, CCL14, CCL16 and CCL22 comparisons for RA and OA SF and serum. (A) shows CCL7 levels to be higher in RA SF compared to OA SF, RA serum and OA serum at p < 0.01. (B) shows the presence of CCL14 in RA and OA. (C) shows CCL16 to be higher in RA serum compared to RA SF and OA SF at p < 0.001.(D) shows CCL22 as increased in RA serum compared to OA SF at p < 0.05. The vertical bar indicates overall range, the box shows interquartile range with horizontal line in the box showing median (RA n = 17, OA n = 7) Kruskal- Wallis ANOVA was used followed by the Dunn’s multiple comparison test *p = <0.05, **p = <0.01, ***p = <0.001.
