Mean ± SEM of cognitive test scores stratified according to APOE genotype and HRT use. Significant P values for APOE genotype, HRT, and APOE*HRT are shown, using the ANCOVA model (MANCOVA for RBANS scores). p-HRT within each APOE genotype is calculated using the pairwise comparison of the estimated marginal mean with Bonferroni adjustment for multiple comparison. Age, years of education, marital status, handedness, and CDR were used as covariates. HRT hormone replacement therapy, MMSE Mini-Mental State Examination, RBANS Repeatable Battery for the Assessment of Neuropsychological Status. FMT four mountain test, SMT supermarket trolley test. P-significant <0.05. a insignificant after FDR correction for multiple comparison. Bold: significant after FDR correction
