  1. aPatients with pSS included in pooled tear sample only. bAutoantibody production was assessed by ELISA. cValues are in mm/5 minutes; normal flow >5 mm/5 minutes. The + symbol indicates dryness and tear secretion <5 mm/5 minutes. dValues are in ml/15 minutes; normal flow >1.5 ml/15. The + symbol indicates dryness and stimulated whole saliva secretion <3.5 ml/5 minutes
