GIANT Consortium 2012-2015 Data File Description:
Each file consists of the following information for each SNP and its association to the specified trait based on meta-analysis in the respective publication. Significant digits for the p values, betas and standard errors are limited to two digits to further limit the possibility of identifiability.
MarkerName: The dbSNP name of the genetic marker
Allele1: The first allele (hg19 + strand). Where the regression coefficients (betas) are provided, the first allele is the effect allele. Where betas are not provided (typically the 2010 data), the first allele is the trait-increasing allele.
Allele2: The second allele (hg19 + strand)
Freq.Allele1.HapMapCEU: The allele frequency of Allele1 in the HapMap CEU population
b: beta
SE: standard error
p: p-value after meta-analysis using regression coefficients (beta and standard error), and after correction for inflation of test statistics using genomic control both at the individual study level and again after meta-analysis
N: Number of observations
