Diagnostic evaluation and classification criteria in Sjögren's Syndrome.

Objectives: Our objective is to carry out a clinical study of the performance of the preliminary European classification criteria for Sjögren Syndrome and that of the criteria proposed by the American European Consensus Group.

Methods: Eighty-eight patients who had undergone a biopsy of the salivary gland on suspicion that they were suffering from Sjögren Syndrome were studied by two independent rheumatologists. Two pathologists independently revised the biopsies without knowing the diagnosis.
