Levels of anti-class A scavenger receptors IgG in patients and healthy individuals. The optical density (OD) value for each individual is represented as a single point. Dashed lines indicate the OD values that exceed the mean control value by more than three standard deviations (SDs). Horizontal bars represent the mean values for each group. CONTROL, healthy donors; pSS, primary Sjögren syndrome; RA, rheumatoid arthritis; SLE, systemic lupus erythematosus. A. Levels of anti-SRCR IgG for patients. B. Levels of anti-SR-A IgG for patients.
