To examine the association between height-associated
genetic variants and CAD, we extracted summary
association statistics for these variants for the
cohorts that contributed to the meta-analyses of
genomewide association studies of CAD performed
by the Coronary Artery Disease Genomewide Replication
and Meta-Analysis (CARDIoGRAM) Consortium5
and the Coronary Artery Disease (C4D)
Consortium.6 Of the 180 SNPs, 112 were also
included on the Metabochip array, a customized
array containing 200,000 SNP markers.16 We
also extracted data for these 112 SNPs from the
Metabochip-array CAD meta-analysis performed
by the combined CARDIoGRAM+C4D Consortium
for cohorts that were not included in the
previous CARDIoGRAM or C4D meta-analyses.7
Each of the studies that were included in these
meta-analyses adhered to a case–control design,
including some nested within cohorts.5-7
