  • **P<0.01.

  • *Cases were considered to be smokers if they had ever smoked >10 cigarettes a day for at least 6 months.

  • †Hypertension was diagnosed if blood pressure >149/90 mm Hg or on antihypertensive treatment.

  • ‡Hypercholesterolemia was diagnosed if total cholesterol >5.0 mmol (193 mg/dL) and/or hypertriglyceridaemia (ever) (triglycerides>1.8 mmmo/L (150 mg/dL) or on antidyslipidaemia treatment.

  • §Diabetes mellitus was diagnosed according to WHO definitions6 (diabetes symptoms plus: HbA1c ≥ 6.5% (48 mmol/mol) or a random venous plasma glucose concentration ≥11.1 mmol/L or a fasting plasma glucose concentration ≥7.0 mmol/L or 2-hour plasma glucose concentration ≥11.1 mmol/L 2 hours after 75 g anhydrous glucose in an oral glucose tolerance test) or on antidiabetic treatment.

  • JCL, juxtacortical lesions; VRF, vascular risk factor.
