Among people who have had blood clots, men are twice as likely as
women to have them again after finishing treatment, according to an
analysis of several studies.

There is no discernible difference in the risk of a
first blood clot between men and women. When it comes to recurrent
thrombosis, however, McRae concludes that men appear to be
statistically at higher risk.

McRae said that the discrepancy is significant enough that physicians should take gender into account when treating patients.
