To provide a more precise evaluation of the association between the (CA)n variations of ALR and the risk for DR, a meta-analysis was performed in the present study.
Overall, the pooled ORs showed a nonsignificant association between ALR C(-106)T polymorphism and DR susceptibility in all genetic models (C allele versus T allele: OR = 1.08, 95% CI = 0.90-1.29; CT/TT versus CC: OR = 0.90, 95% CI = 0.72-1.13; TT versus
