Fig. 2From: Multivariate analysis of the effect of Chalazia on astigmatism in childrenIncidence of astigmatism according to different groupings. A Comparison of the incidence rate of astigmatism in patients with a single chalazion at different sites. B Comparison of the incidence rate of astigmatism by mass size in patients with a single chalazion. C Comparison of the incidence rate of astigmatism between groups with specific numbers of chalazion masses. *indicates a difference in the incidence rate of astigmatism (P < 0.05)Back to article page
