Fig. 6From: Poor statistical power in population-based association study of gene interactionThe interaction coefficient and level of significance contributes to power1 and power2. A-D The figures show the relationship between power1, power2, and K under three groups of \(f_{1*}\) when level of significance ≤ 5.0 × 10–2, ≤ 5.0 × 10–4, ≤ 5.0 × 10–6, and ≤ 5.0 × 10–8, respectivelyBack to article page
