Abbreviations: ESSDAI EULAR Sjögren Syndrome Disease Activity Index, EULAR European League Against Rheumatism, PSL prednisolone
Glucocorticoid dosages were graded as high (prednisolone (PSL) ≥ 0.5 mg/kg/day or equivalent), medium (PSL ≥0.2 but < 0.5 mg/kg/day or equivalent) and low (PSL < 0.2 mg/kg/day or equivalent)
One patient did not have any active domains
