  1. Model: WT = the base model with no cofactor. WT|SMK = the conditional model with smoking as a cofactor.
  2. Heritability: \(h_{A}^{2}\) = heritability of additive effects; \(h_{D}^{2}\) = heritability of dominance effects; \(h_{I}^{2}\) = heritability of epistasis effects including AA, AD, DA, DD; \(h_{AE}^{2}\) = heritability of ethnicity-specific additive interaction effects; \(h_{DE}^{2}\) = heritability of ethnicity-specific dominance effects; \(h_{IE}^{2}\) = heritability of ethnicity-specific epistasis effects including AAE, ADE, DAE, DDE; \(h_{T}^{2}\) = total heritability.
