Figure 1.

A, Prevalences of intracranial stenosis of 50% or greater or occlusion are shown according to the severity of extracranial carotid atherosclerosis. The P value for the trend was .002 and was calculated including the severity as the ordinal variable. B, Prevalences of intracranial stenosis of 50% or greater or occlusion are shown according to the severity of coronary atherosclerosis. The P value for the trend was .004 and was calculated including the severity as the ordinal variable.
