  1. BFs are expressed relative to the null model for total grey matter (GM), frontal, parietal, temporal occipital lobe ROIs. All BFs are corrected for age, sex and site. Bolded values indicate the strongest of the alternative models preferred over the null model (BFs > 1) for a given ROI; in both GM and temporal ROIs, this was M2: [Control = SCD] < MCI < AD. Values in square brackets are the BFs comparing the preferred alternative model directly to the other alternative models for that ROI. In frontal, parietal and occipital ROIs, results favoured the null model (all BFs < 1).
