APOE and dementia: In analysis where the entire cohort was dichotomized based on grip strength and APOEƐ4 allele into four groups (Figure 3), compared with women with no APOEƐ4 and higher grip strength (n = 379), women with weak grip strength and APOEƐ4 (n = 179) had 3.19 times higher hazard for a late‐life dementia event.
