Number Needed to Treat
How many people have to be treated to prevent a future bad outcome?
Clinicians ultimately want number needed to treat to be LOW, meaning that few people need to be treated to prevent a bad outcome. As the absolute risk reduction decreases, denoting a small treatment effect, the number needed to treat will increase and more people will have to be treated to prevent a bad outcome.
