Before revision:  We applied Gaussian graphical models (GGMs) for analyzing the conditional dependency networks of multimodal neuroimaging dataand assessed alterations of the network structure in mild cognitive impairment (MCI) and Alzheimer's dementia (AD) compared to cognitively healthy controls.
After revision:  We applied Gaussian graphical models (GGMs) can estimate the conditional dependency networks of multimodal neuroimaging dataand assessed alterations of the network structure in mild cognitive impairment (MCI) and Alzheimer's dementia (AD) compared to cognitively healthy controls.
