CCL2 and Alzheimer disease: Logistic regression analysis regarding MCP-1 genotype distribution adjusted for age and APOEe4 was applied to these populations and results were not statistically significant; therefore age and APOEε4 presence did not affect MCP-1 genotype distribution (AD vs CTR p=0.713, AD vs MCI p=0.299, MCI vs CTR p=0.988) and MCP-1 genotype was not an independent risk factor for AD or MCI.
