Quantile-Quantile plots of T2D association analysis results based on FHS data using a CC-GWAS, b LT-FH, and c Fam-meta. Each plot represents expected -log10 P-values vs. observed -log10 P-values. The gray line denotes y = x, and deviation from the line represents deviation of actual P-value from expected P-value under the null hypothesis. The genomic control factor λGC is also shown on each plot
