Real-World Diagnostic Performance of OMERACT Salivary Gland Ultrasound in Patients Evaluated for Sicca Symptoms

J RheumatolPublished Diagnostic accuracy study

Authors' conclusion

In real-world settings, SGUS using the OMERACT score demonstrates high specificity, particularly in PGs, and moderate sensitivity, outperforming UWSFR in younger patients.
