*Autoantibody production was assessed by ELISA.
**Values are the number of focal infiltrates/4 mm2 tissue area containing >50 mononuclear cells.
***Values are in mm/5 minutes; normal flow >5 mm/5 min. “+” indicates dryness and tear secretion ≤5 mm/5 minutes.
****Values are in ml/15 minutes; normal flow >1.5 ml/15 minutes. “+” indicates dryness and unstimulated whole saliva secretion ≤1.5 ml/15 minutes.
