  1. Interaction term p value, 2 × 2 factorial ANOVA. The independent variables consisted of indicator variable values (e.g., R allele = 1; S allele = 2) assigned to each rat based on the genotypes for D2mgh11 (α1NK, factor 1) and for D3mit3 (NKC, factor 2) markers. 2 × 2 factorial analysis was done independently for SBP, DBP, and MAP.
