Conditional effect of APOE × education at values of gender | ||||||
Gender | Effect | SE | t value | p value | Lower LCI | Upper LCI |
Man | −10.38 | 5.38 | −1.93 | 0.05 | −20.96 | 0.19 |
Woman | 2.38 | 1.67 | 1.43 | 0.15 | −0.90 | 5.65 |
Note: The variables, APOE, gender, and education were mean-centered prior to analysis. Gender: man = 1, woman = 2; APOE ε4 allele: the ε4 noncarriers = 0, the ε4 carriers = 1; education: low = 1, middle = 2, high = 3
