Figure 1. Antibodies against IFI16 are detected in patients with SS, but not in healthy controls.

Figure 1

Serum IgG antibodies against IFI16 were assayed by ELISA in patients with SS (n = 133) and healthy controls (n = 47), as described in the Methods and Results sections. Each symbol represents the IFI16 antibody level in a single patient serum. Antibodies were detected in 38/133 (29%) of SS patients, and 1/47 (2.1%) of controls. The dotted line marks the cutoff for assignment of a positive score.
