Note: Because neither the main effect for zygosity (IRR = 1.05, 95% CI = 0.83 to 1.34, p = .675) nor the zygosity x within-pair disadvantage effect (IRR = 0.95, 95% CI = 0.85 to 1.07, p = .3924) was significant, these predictors were not included in the models.
WP = within-pair, BP = between-pair
= p < .05
= p < .01
