Flowchart of patients excluded from the study and included patients randomized to active treatment with 5 mg/d donepezil or placebo. TIA indicates transient ischemic attack. *Patients might have >1 reason for screen failure, and some patients were screened more than once. †Twenty-five patients were excluded from the ITT population because they did not have a baseline assessment in addition to at least 1 postbaseline assessment for at least 1 of the primary efficacy variables. ‡Eleven patients died during the study (all in the donepezil group).
