Figure 1: Cumulative incidences of ischemic stroke of dementia patients who were or were not treated with acetylcholinesterase inhibitors.
From: Association between acetylcholinesterase inhibitors and risk of stroke in patients with dementia

Data were compiled after adjustment for competing mortality. For cumulative incidences of ischemic stroke, calculation and comparison in competing risk data ratios were conducted using modified Kaplan-Meier and Gray methods.
