An additional exploratory analysis showed a borderline significant correlation between higher logarithmic HOMA-IR and a higher [ 11 C]PIB SUVR composite score in the APOE4 / 4 group (rho = 0.44, p = 0.06), whereas there was no association in APOE3/3 (rho = 0.16, p = 0.50) or APOE3/4 (rho = −0.052, p = 0.82) carriers.
