Description of the Subjects Who Evaluated 1 of 3 Treatment Scenarios for Symptomatic Carotid Stenosis^*

Subjects	Aspirin All, RB†/BR	CEA All, RB†/BR	EC/IC All, RB†/BR	P Value‡
Age, y	39.1, 38.7/39.6	37.8, 36.6/36.8	37.5, 35.6/39.3	.22
Familiarity with stroke, 0–100	62.4, 62.4/61.9	61.8, 62.5/61.2	58.7, 57.4/60.0	.32
Having used treatment, %	22, 20/23	0, 0/0	0, 0/0	<.001

^*Mean values for all subjects randomized to each treatment of stroke are shown first, followed by mean values in each of the two information order arms.

^†For each treatment of stroke, the characteristics of the subjects in the 2 information order arms (RB = Risk then Benefit Information, BR = Benefit then Risk Information) were not significantly different (P > .05).

^‡P values are for comparison across treatment arms.

CEA, carotid endarterectomy surgery; EC/IC, extracranial-intracranial bypass surgery.
