Distribution of peripheral blood B cell population in ANA-positive and ANA-negative JIA patients. (A) Frequency of peripheral blood CD19+ B cells within lymphocytes as well as different B cell populations within CD19+ B cells in a cohort of JIA patients (n = 45) and same number of age- and sex-matched healthy control (HC) individuals. Bars represent mean frequency with standard deviation and circles individual data points. (B) Frequency of these B cell populations from JIA patients was compared between ANA+ and ANA– patients. Groups were compared using unpaired Student's t-test.
