Evaluate the diagnostic accuracy of OMERACT SGUS in routine clinical practice for Sjögren's disease.
Conducted a prospective study with 103 outpatients referred for dryness evaluation.
Performed blinded salivary gland ultrasound on parotid and submandibular glands with OMERACT scoring.
Defined positivity as a score ≥2 in at least one gland.
SGUS sensitivity was 66.7% and specificity was 76.9%.
Parotid gland analysis showed high specificity at 92.3% but lower sensitivity at 49.0%.
Submandibular gland demonstrated higher sensitivity at 58.8% but lower specificity at 78.8%.
