Results of linear regression models with indicators of cerebral small vessel disease as variables and Z-scores of executive functioning as outcome.

The explained variance (R2) in executive functioning is given for each model with the corresponding p-value for the difference in explained variance (Δ R2) between the model and the previous model. Unstandardized coefficients (B) with corresponding 95% CIs are provided. LL: lacunar lesion. WML: white matter lesion. SLF: superior longitudinal fasciculus. ATR: anterior thalamic radiation. Presence of LLs (which corresponds with presence of LLs anywhere in the brain) was entered as a dichotomous variable; all other variables were entered as continuous variables. aThese results suggest that LLs in the anterior thalamic radiation (B = −3.12) might have greater impact on executive functioning than LLs in the superior longitudinal fasciculus (B = −1.20).
