What are the findings of studies regarding sex differences in short-term case fatality rates?
Studies that have examined sex differences in short-term case-fatality rates (commonly defined as within 30 days of onset and inclusive of all strokes) have been quite variable and are complicated by a lack of age adjustment. Some studies have reported that women have higher case fatality whereas others have not. However, studies that have adjusted for age (as well as other characteristics) show that the sex difference in short-term mortality can actually reverse, with women having lower mortality after adjustment.
