Lacunes		41%		24%		OR 2.2 (0.7 to 7.0)
Lacunes and/or cortical infarcts		47%		27%		OR 2.4 (0.8 to 7.8)

Mean difference is the unadjusted between group difference (diabetes minus no diabetes) in the linear regression analysis, with 95% confidence interval in brackets. OR for AD/DM2 relative to AD/non‐DM. Adjustment for age or hypertension did not affect the results. Data are median (quartiles), or proportions. *p<0.05.
