CCL11 and Alzheimer disease: Even though the frequency of the T allele was slightly higher in AD cases than that in controls (13% vs 9%), no significant association was found between the CCL11 − 426C/T polymorphism and AD risk under 5 genetic models (C vs T: OR = 0.73, 95% CI = 0.47–1.12, P = .15; CC vs TT: OR = 1.24, 95% CI = 0.26–5.88, P = .79; TC vs TT: OR = 1.90, 95% CI = 0.37–9.80, P = .44; CC + TC vs TT: OR = 1.37, 95% CI = 0.29–6.60, P = .69; CC vs TC + TT: OR = 0.67, 95% CI = 0.42–1.07, P = .09) (Fig. 4).
