So I googled "what is the NNT for Lipitor" This is what I got.
"So to spare one person a heart attack, 100 people had to take Lipitor for more than three years. The other 99 got no measurable benefit. Or to put it in terms of a little-known but useful statistic, the number needed to treat (or NNT) for one person to benefit is 100."
I guess that is not so great, right?
