  1. INVFCortex = intra-neurite volume fraction representing neurite density in the cortex, INVFWM = intra-neurite volume fraction representing neurite density in the white matter, ODICortex = orientation dispersion index of neurites in the cortex, ODIWM = orientation dispersion index of neurites in the white matter, ISOCortex = isotropic diffusion in the cortex, ISOWM = isotropic diffusion in the white matter, VOLCortex = cortical volume, VOLWM = white matter volume; Sex was represented as a dummy variable with males being labeled 0 and females 1; *p < 0.05
