Note. The coefficients are based on the Model 3 (unadjusted) and Model 4(sibling comp), without the moderating effects of offspring gender (thus the coefficients are the same for males and female). Only coefficients based on MAC are presented. Full results available upon request. p < .05 for all estimates for first-born offspring. Estimates for second and third-born offspring are based on the interaction of MAC and MAC*birth order terms.
