The operation, in which an artery on the scalp is attached to an artery on the brain

Question

to bypass a partial or total blockage, costs about $15,000. In a new study, researchers from the University Hospital in London, Ontario, examined 1,377 people who had recently had strokes or had signs of impending strokes. They randomly assigned 714 to get standard medical care and 663 to get EC/IC bypasses. The group that had the surgery subsequently had a slightly higher rate of stroke and death than the control group, according to the study.-Reported in the New England Journal of Medicine

What will be an ideal response?

Answer 1

Remind us not to spend $15,000 on an EC/IC bypass. People who received standard medical care were part of the control group, while people who got the EC/IC bypasses were the experimental group.
