title: Summary of design features: clinical trials of platelet-active drugs in cerebrovascular disease.
abstract: Two randomized, double-blind clinical trials in cerebrovascular disease are described. The Controlled trial of Aspirin in Cerebral Ischemia compared aspirin (650 mg twice daily) with placebo in medically and surgically treated groups of patients who had experienced transient ischemic attacks. The Randomized Trial of Aspirin and Sulfinpyrazone in Threatened Stroke compared aspirin (325 mg four times daily), sulfinpyrazone (200 mg four times daily) and aspirin plus sulfinpyrazone with placebo in patients with transient cerebral ischemia.
