Protein data was obtained by liquid chromatography tandem mass spectrometry technique in whole saliva from 24 patients with pSS and 16 patients having symptoms of pSS, but not fulfilling the American College of Rheumatology\/European League against Rheumatism classification criteria (non-pSS). Serum anti-SSA\/Ro antibody was measured using enzyme-linked immunosorbent assays.

ROC analysis showed that salivary levels of TRIM29 alone enabled differentiation between pSS and non-pSS with an area under curve (AUC) of 0.88 (95%CI 0.77\u20131.00).
