Table 4.
The intercepts and coefficients for age (Cage) and gender (cgender) obtained from the linear regression analyses of the PVSV mean apparent diameter, VF, count, and rCNR in the thalamus, BG, midbrain, and WM ROIs. Values in the parentheses are standard errors. The asterisks denote coefficients that were significantly different from zero (corrected p ≤ 0.05) after FDR correction.
