WebbIn other words, a typical GWAS will report summary statistics in which the effect of each variant is calculated independently. However, there are many other regression frameworks in which the effects of the variants are calculated all at the same time, which provides critical adjustments that limit the confounding caused by linkage disequilibrium.
