## Association results of the meta-analysis for intelligence based on 78,308 individuals in 13 cohorts.
## Version date: 10-07-2017
#Columns:
Chromosome: chromosome number
position: base pair position of the SNP on the chromosome (reported on GRCh37)
rsid: SNP rs number
ref: effect allele
alt: non-effect allele
N: sample size
MAF: minor allele frequency in UK Biobank
Beta: effect size of the effect allele
SE: standard error of the effect
Zscore: Z-score computed in METAL by a weighted Z-score method
p_value: P-value computed in METAL by a weighted Z-score method
direction: direction of the effect in each of the cohorts, order: CHIC (consisting of 6 cohorts), UKB-wb, UKB-ts, ERF, GENR, HU, MCTFR, STR
Beta/SE were calculated from METAL Z-scores using the formula from Zhu et al (Nature Genetics, 2016):
Beta = Zscore / sqrt( 2 * MAF * ( 1 - MAF) * ( N + Zscore^2 ) )
SE = 1 / sqrt( 2 * MAF * ( 1 - MAF ) * ( N + Zscore^2 ) )
