We performed a correlation analysis between T cell clusters and a range of clinical parameters—age, gender, disease duration, disease activity scores (DAS28-CRP and SDAI), patient-reported VAS, and serum markers (CRP, MMP-3, ACPA, and RF)—in a cohort of 33 patients with RA (Supplementary Figure 9). The gene discussed is CRP; the disease is rheumatoid arthritis.
