The primary
end-point event rates in the group with transient
ischemic attack were lower than expected, which
raises the possibility that we enrolled some patients with nonischemic conditions mimicking a
transient ischemic attack, in whom antiplatelet
therapy is unlikely to be efficacious. Patients who
underwent thrombolysis or thrombectomy were
not eligible for participation in this trial, so the
results should not be generalized to them.
