Compared to those excluded (n = 1131, Figure 1), participants who were followed up (n = 2052) had a higher mean age at baseline (P < .001), were more likely women (P < .001), and had a lower frequency of APOE ɛ4 carriers (P < .001), while no differences were found in AD‐PRSs (the 39‐SNPs AD‐PRS and 1e–5 AD‐PRS) or median age at death. The gene discussed is APOE; the disease is Alzheimer disease.
