The pooled results showed significant differences in clinical symptoms disappear (dry mouth and dry eyes) (p = .0004), IgM (p < .00001), IgA (p < .00001), salivary flow rate (p < .00001) and Schirmer's test (p = .02) in the comparison of TGP combined with HCQ and HCQ alone. Here, CD79A is linked to xerostomia.
