Comparison of chemokine and IFN scores between SLE and RA patients, and healthy donors. The methods employed to calculate the chemokine score and the IFN score are described in Materials and methods. (a) Chemokine scores were significantly elevated in SLE patients versus RA patients and healthy donors. (b) IFN scores were significantly elevated both in SLE and RA patients versus healthy donors. (c) Chemokine scores were positively correlated with IFN scores in SLE patients. Each symbol represents an individual patient; horizontal lines indicate median values. IFN, interferon; RA, rheumatoid arthritis; SLE, systemic lupus erythematosus.
