F female, FI fatty infiltration, NT not tested

*Autoantibody production was assessed by ELISA

**Values are the number of focal infiltrates/4mm² tissue area containing > 50 mononuclear cells

***The degree of fatty infiltration was assessed and the sections were scored blindly, where no or little fatty infiltration = 0, moderate = 1, and prominent = 2

****Values are in mm/5 min; normal flow > 5 mm/5 min. ‘+’ indicates dryness and tear secretion ≤ 5 mm/5 min

*****Values are in ml/15 min; normal flow > 1.5 ml/15 min. ‘+’ indicates dryness and unstimulated whole saliva secretion ≤ 1.5 ml/15 min
