In the SLE group, MDC concentration was positively correlated with body mass index (BMI) (r = 0.445, p = 0.005), and IL-5 level was negatively correlated with high-density lipoprotein (HDL) concentration (r = 0.461, p = 0.003) (Supplementary Table S6). The gene discussed is CCL22; the disease is systemic lupus erythematosus.
