∗One-way ANOVA analyses: comparison among controls, patients with DM without DR, and patients with DR. Statistical significance was set at p = 0.002 after Bonferroni's correction. Comparison versus controls: †Scheffé's test, p = 0.001; ‡Scheffé's test, p = 0.002; Scheffé's test, p < 0.0001; #Scheffé's test, p = 0.0004.
