ASPS-Fam: Austrian Stroke Prevention Family Study, N: number of individuals in analyses, VMR: vitamin D metabolite ratio, β: regression coefficient, SE: standard error of regression coefficient, p: p-value.

All analyses are adjusted for age, sex, hypertension, diabetes, atrial fibrillation, season at blood draw and family structure. All Freesurfer variables are normalized for total intracranial volume.
