Correcting "winner's curse" in odds ratios from genomewide association findings for major complex human diseases.

Abstract excerpt

Genome-wide association studies (GWAS) provide an important approach for identifying common genetic variants that predispose to human disease. However, odds ratio (OR) estimates for the reported findings from GWAS discovery data are typically affected by a bias away from the null sometimes referred to the "winner's curse". Also standard confidence intervals (CIs) may have far from the desired coverage rates. We...
