Soluble Markers of Antibody Secreting Cell Function as Predictors of Infection Risk in Rheumatoid Arthritis

Figure 4

Box plots comparing serum sBCMA protein levels among RA patients with and without infections and healthy donors. Levels of sBCMA in healthy controls (HC, left white box; ), RA patients without infections (middle gray box; ), and RA patients with infections (right gray box; ) are shown. Patients with RA with a history of infections had significantly lower sBCMA levels compared to RA subjects without a history of infections () and to healthy controls (). .
