Column MA coding shows compound genotypes coded by the number of minor alleles (0, 1, or 2) in each SNP ordered as rs429358, rs2075650 and rs12721046. Symbols “X” and “Y” denote aggregated compound genotypes; these symbols take values of 0, 1, or 2 but not simultaneously 0.
Column Sample shows the results for the pooled sample and the AD Genetics Consortium (ADGC) sample, and the results from the meta-analysis of the pooled and ADGC samples. The pooled sample includes the NIA Late Onset Alzheimer’s disease Family Study, the Health and Retirement Study, the Cardiovascular Health Study, and the Framingham Heart Study original and offspring cohorts. Ntotal is the total number of subjects; NAD is the number of AD cases; SE is the standard error.
