Figure 3. Correlations between EC-SOD and VEGF levels (for vitreous body and serum). A: Intravitreal EC-SOD showed a significant correlation with intravitreal VEGF. The correlation coefficient was 0.61, and the p value was p<0.001. B: In the serum, there was no significant correlation between EC-SOD and VEGF. For vitreous body data, open circles represent MH patients and closed circles indicate PDR patients. For serum data, open triangles represent MH patients and closed triangles indicate PDR patients. Correlations were examined using Spearman rank-correlation coefficient, and the number of each group was follow: the vitreous samples of PDR (n=14) and MH (n=14), the serum samples of PDR (n=9) and MH (n=9).
