a IgM, IgG and IgA autoantibodies to SP1 were determined by ELISA in the sera of patients with idiopathic dry eyes and Schirmer’s tests < 3 mm (27 patients), Schirmer’s tests < 6 mm (38 patients) or normal controls (35 patients). Data shown are the percent positive in each group for each of these autoantibodies. b IgM, IgG and IgA autoantibodies to CA6 were determined by ELISA in the sera of patients with idiopathic dry eyes and Schirmer’s tests < 3 mm (27 patients), Schirmer’s tests < 6 mm (38 patients) or normal controls (35 patients). Data shown are the percent positive in each group for each of these autoantibodies. c IgM, IgG and IgA autoantibodies to PSP were determined by ELISA in the sera of patients with idiopathic dry eyes and Schirmer’s tests < 3 mm (27 patients), Schirmer’s tests < 6 mm (38 patients) or normal controls (35 patients). Data shown are the percent positive in each group for each of these autoantibodies
