Figure 3.
Age and cognitive functions versus regional efficiency for the FA-weighted networks of the 68 cortical areas (34 in each hemisphere). Partial correlation analyses were carried out. Age, sex, and years of education were controlled for in the cognitive function versus regional efficiency analyses (including processing speed, language, executive, memory, and visuospatial). In the age versus regional efficiency analyses, sex and years of education were controlled for. To correct for multiple comparisons, we used FDR to calculate the new thresholds for p values, and 0.0320, 0.0363, 0.0190, and 0.0025 were used for the multiple comparisons for age, processing speed, and visuospatial and executive functions, respectively. The colors of the nodes refer to: red, significant after FDR correction for multiple comparisons; green, p < 0.05, significant before FDR correction; blue, p ≥ 0.05, not significant.
