CES-D = Center for Epidemiologic Studies Depression Scale.
Mood = Center for Epidemiologic Studies Depression Scale Depressed Mood subscale.
WMHs = white matter hyperintensity ratings.
-- indicates variables that were dropped from the model by backward elimination.
*
indicates significance at p <.05.
**
indicates significance at p <.01.
