Figure 1.

Spearman's rank correlation between titers of autoantibodies and dry eye parameters. The anti-dsDNA and C3 showed significant correlations with KSen, SPK, and Schirmer. No correlations of dry eye parameters were observed between C4, ESR, and ANA. ANA = antinuclear antibodies; anti-dsDNA = antidouble-stranded DNA antibody; C3, C4 = complement levels; ESR = erythrocyte sedimentation rate; KSen = corneal sensation; NS = not significant; P = P-value; r = Spearman's correlation coefficient; Schirmer = Schirmer-I test; SPK = superficial punctate keratopathy; TBUT = tear-film break-up time. ^∗RGB.
