Design outcomes

Primary

Measure	Time frame
Sonographic diagnostic ability for confirmed diagnosis Diagnostic method: From the heterogeneity of internal echoes and atrophy of the glands, the confidence score as Sjogren's syndrome (SS) is evaluated in 5 grades (5: certainly SS, 1: definitely not SS).	—

Secondary

Measure	Time frame
Correlation of sonographic diagnostic ability and various factors such as imaging conditions at the time of examination, operator's experience, examination frequency and diagnostic ability	—
