There were nonsignificant increases in CXCL13 (median levels RA = 68.34 pg/ml vs. controls = 51.89 pg/ml, p = 0.24), in CXCL10 (median levels RA = 34.73 pg/ml vs. controls = 24.09 pg/ml, p = 0.07), and in CXCL11 (median levels RA = 47.30 pg/ml vs. controls = 61.90 pg/ml, p = 0.07) in the unadjusted comparison (Figure 2). Here, CXCL13 is linked to rheumatoid arthritis.
