Application of the OMERACT Grey-scale Ultrasound Scoring System for salivary glands in a single-centre cohort of patients with suspected Sjögren's syndrome.

The OMERACT Ultrasound Scoring System showed good sensitivity (0.72) and excellent specificity (0.91) for fulfilling 2016 ACR/EULAR criteria using cut-off score >2 in at least one gland. Our data supports the use of ultrasound for diagnosing pSS and supports incorporation of ultrasound in the classification criteria.
