  • a The variables explaining unique variance within each method, as listed in Table 2, were included in the set of predictor variables, i.e. for MR: hippocampal volume, retrosplenial, and entorhinal thickness; for PET: entorhinal, retrosplenial, and lateral orbitofrontal metabolism; and for CSF: the ratio of T-tau to Abeta 42. R2 is Nagelkerke R2.
