Significant coefficients and p-values are in bold font (p < 0.05). Model 1 was adjusted for gender, age, years of education and brain size index; Model 2 was additionally adjusted for GDS score, self-reported anxiety, hypertension, hyperlipidemia, diabetes mellitus, heart disease and lifestyle of smoking.
