Risk of vascular dementia by onset of dementia (early onset: age at diagnosis or end of follow-up <65 years, late onset: age at diagnosis or end of follow-up ≥ 65 years), BMI and sex for individuals 70 years or less at baseline in the primary care cohort. Models adjusted for age, BMI, sex and smoking status. Models in subgroups further adjusted for an interaction term between BP and age at event (plotted, Onset subgroup), BMI categories and an interaction term between BP and BMI categories (plotted, BMI subgroup), an interaction term between BP and sex (plotted, sex subgroup). No. VaD refers to the number of vascular dementia events.
