Multiple linear regression analysis was used to analyze the relationship between cognitive score and rCBF in different region. The B value represents the regression coefficient of the rCBF after adjusting age and education level.
rCBF: relative cerebral blood flow: CBF values of the associated cortex/ipsilateral cerebellum; L: left; R: right; LFC: lateral frontal cortex; MFC: medial frontal cortex; CSO: centrum semi-oval; PC: parietal cortex; TC: temporal cortex.
