For a subgroup of CAD cohorts in which we
had access to individual-level genotypes genomewide
(Table S3 in the Supplementary Appendix),
we performed a weighted analysis of genetic
risk score to evaluate the effect of the
presence of an increasing number of heightrelated
variants on the risk of CAD. We calculated
a value of 0 to 2 for every SNP for each
individual on the basis of the sum of the posterior
probabilities for the height-increasing
allele and multiplied by the effect size observed
for height. We then totaled these values across
all SNPs for each individual, and the individuals
were then grouped into quartiles. We used logistic
regression to assess the quartiles, after adjustment
for study, to estimate combined odds
ratios for CAD
