  • a The variables explaining the unique variance within each method, as listed in Table 2, were included in the set of predictor variables (ie, for MR imaging, hippocampal volume and retrosplenial and entorhinal thickness; for PET, entorhinal, retrosplenial, and lateral orbitofrontal metabolism; and for CSF, the ratio of t-τ:Aβ42).

  • b P < .05, corrected for 7 comparisons.
