Women and Statins

A question to us about Letter #48: What is the evidence of benefit for primary prevention in women?

There were 10,990 women in the primary prevention trials (28% of the total). Only coronary events were reported for women, but when these were pooled they were not reduced by statin therapy, RR 0.98 [0.85-1.12]. Thus the coronary benefit in primary prevention trials appears to be limited to men, RR 0.74 [0.68-0.81], ARR 2.0%, NNT 50 for 3 to 5 years.
