Figure 1: Box plot showing distribution of 8-hydroxydeoxyguanosine levels between cases and controls of (a) pseudoexfoliation glaucoma (PXG), (b) males and females, (c) LOXL1 rs1048661 genotypes, and (d) LOXL1 rs3825942 genotypes. Differences were tested by the Mann–Whitney U test both within and between the study groups. Significance was observed only between cases and controls and between control males vs. PXG males as indicated in (a) and (b), respectively. No other significant distribution was observed.
