Before revision:  Graph-theoretical statistics were calculated to determine network alterations associated with disease severity. Network measures clustering coefficient, path length and small-world coefficient 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 ADpatients compared to controls.
After revision:  Graph-theoretical network statistics 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 ADpatients compared to controls.
