CCL2 and systemic lupus erythematosus: Similarly, CCL2 was significantly associated with IFN score in patient visits with low STAT1 SLE (r2 = 0.07, P <0.0010), patient visits with high-STAT1 SLE (r2 = 0.76, P <0.0001), and HD with low STAT1 (r2 = 0.08, P = 0.0002); also CXCL10 displayed significant association with IFN score for SLE patients with low STAT1 (r2 = 0.09, P = 0.0003), patient visits with high STAT1 SLE (r2 = 0.30, P = 0.0008), and HD with low STAT1 (r2 = 0.08, P = 0.027, Figure 7B, C).
