However serum levels of CXCL1 (205 ± 143, median 167 pg/ml vs. 160 ± 76, median 147 pg/ml, respectively; p = 0.249), CXCL9 (313 ± 232, median 239 pg/ml vs. 294 ± 239, median 238 pg/ml, respectively; p = 0.725), CXCL13 (30 ± 40, median 21 pg/ml vs. 20 ± 8, median 16 pg/ml, respectively; p = 0.161) and CXCL16 (656 ± 187, median 648 pg/ml vs. 663 ± 202, median 657 pg/ml, respectively; p = 0.827) were not different between BD patients and HCs (Fig. 1). The gene discussed is CXCL1; the disease is Behcet disease.
