Abbreviation: TIA, transient ischemic attack.

a

One participant randomized to the medical therapy alone group was not included due to missing outcome data. See Figure 1.

b

Adjusted for site effect.

c

Log-rank test adjusted for site effect.

d

Post hoc analysis.

e

There were 5 ischemic stroke and 4 hemorrhagic strokes. Of the 4 symptomatic hemorrhagic strokes, 1 was periprocedural subarachnoid hemorrhage immediately after percutaneous transluminal angioplasty and stenting (probably related to guidewire perforation); 1 was periprocedural parenchymal and subdural brain hemorrhage evident immediately after percutaneous transluminal angioplasty and stenting (probably related to guidewire perforation); 1 was cerebellar and occipital hemorrhage that occurred 3 days after percutaneous transluminal angioplasty and stenting (probably related to reperfusion); and 1 was subarachnoid hemorrhage within 24 hours after percutaneous transluminal angioplasty and stenting (probably related to reperfusion). A total of 2 of these hemorrhages were fatal (1 developed massive cerebral infarction and brain hernia, and 1 had parenchymal brain hemorrhage), and 2 were nondisabling (1 cerebellar and occipital hemorrhage and 1 subarachnoid hemorrhage).

f

There were 4 ischemic strokes and 0 hemorrhagic strokes. Of the 4 ischemic strokes, 2 were disabling, 2 were nondisabling, and none were fatal.

g

One missing follow-up and 4 died.

h

Four missing follow-up and 0 died.

i

Four missing follow-up and 4 died.

j

Eleven missing follow-up and 1 died.

k

Eight missing follow-up, including 4 with primary outcomes (but no disabling stroke or death).

l

Sixteen missing follow-up, including 5 with primary outcomes (but no disabling stroke or death).

m

Four missing follow-up and 3 died.

n

Ten missing follow-up and 0 died.

o

Sixteen missing follow-up, including 12 with primary outcomes.

p

The causes of death in the percutaneous transluminal angioplasty and stenting group were as follows: brain hemorrhage (n = 2), ischemic stroke (n = 2), sudden cardiac arrest (n = 1), intrahepatic cholangiocarcinoma (n = 1), and aortic artery aneurysm (n = 1).

q

Twenty-three missing follow-up, including 12 with primary outcomes.

r

The causes of death in the medical management group were as follows: ischemic stroke (n = 1) and brain hemorrhage (n = 1).
