The specific types of benefits differ in important ways & in women, by reducing the risk of ischemic stroke, and in men, by reducing the risk of heart attack.

In both men and women, there was an approximately 70 percent increase in the risk of bleeding associated with the taking of aspirin. And it is known that the bleeding risk associated with aspirin is dose-related.

In other words, 81 milligrams a day gives as much benefit as higher doses with potentially less risk of bleeding.

Our study found that aspirin treatment was associated with a 24 percent reduction in the risk of the most common type of stroke in women and a 32 percent reduction in heart attacks in men.

We didn't know if we'd see the benefits in a trial of women at high risk. And in fact, it does hold out.
