ICAM1 and retinal disorder: The pooled effect estimates among all studies did not find statistically significant associations between the ICAM-1 rs5498 polymorphism and retinopathy in type 2 diabetes at the dominant model (GG + GA versus AA, OR = 1.00, 95% CI: 0.66–1.50, P = 0.987), the recessive model (GG versus GA + AA, OR = 1.24, 95% CI: 0.86–1.77, P = 0.245), the GG versus AA contrast (OR = 1.14, 95% CI: 0.68–1.92, P = 0.611), and the G allele versus A allele contrast (OR = 1.08, 95% CI: 0.81–1.45, P = 0.592) (Table 2 and Figs. 2 and 3).
