Data represent the mean ± standard deviation or median and interquartile ranges. Student t-test or Mann–Whitney U test were performed to compare DTI parameters in ROIs between two groups.
Significant values are in [bold].
DTI diffusion tensor imaging, DESH disproportionately enlarged subarachnoid space hydrocephalus, ROI region of interest, iNPH idiopathic normal pressure hydrocephalus, FA fractional anisotropy, MD mean diffusivity, AD axial diffusivity, RD radial diffusivity, Lt left, Rt right.
*Adjusted for multiple comparison corrections using the False Discovery Rate (FDR) method.
