Graphs showing prevalence (%) of cerebral co-incident acute infarction and small vessel disease including white matter hyperintensity lesion, cerebral microbleeds, and silent lacunar infarction by age at the time of cerebral magnetic resonance imaging. The prevalence of cerebral MRI lesions tends to increase with age except cerebral microbleeds. MRI = magnetic resonance imaging. *Significant difference, P < 0.05, χ2 test.
