GWAS power analysis for the PoOxE test for increasing relative risk ratios (increasing values of ${\text{RR}}_{M,2}$; ${\text{RR}}_{M,1}={\text{RR}}_{F,1}={\text{RR}}_{F,2}=1$) and increasing number of case‐parent triads, assuming equally sized exposure groups and $\text{MAF}=0.2$. Left panel: Nominal significance level 10⁻⁴; right panel: Nominal significance level $5\times {10}^{-8}$ [Color figure can be viewed at wileyonlinelibrary.com]
