Figure 1From: ITGB5 and AGFG1 variants are associated with severity of airway responsiveness Quantile-quantile (QQ) plot. Comparison of primary GWAS P-values to those expected for a null distribution. Distribution of genotyped (red) and imputed (blue) GWAS results shows little evidence of deviation of measures at the tail, making the distinction among SNPs having low P-values representing true associations vs. those SNPs having low P-values by chance challenging.Back to article page
