 Network measures clustering coefficient and path length were significantly altered across diagnostic groups, with a biphasic u-shape trajectory , i.e. increased small-world coefficient in early MCI, intermediate values in late MCI, and decreased values in AD patients compared to controls. In contrast, no group differences were found for clustering coefficient and small-world coefficient when estimating conditional dependency networks on single imaging modalities . GGMs showed almost no conditional dependencies between modalitieswhen at the same time considering various other regions within the same modalities.
