Serious gaps: How the lack of sex/gender-based research impairs health

In summary, a broad range of opportunities is available for behavioral scientists and health services researchers interested in enhancing understanding of these diseases and conditions, as well as improving the quality of care and well-being of women and men affected by them. It is essential that women's representation in clinical trials continue to increase; to be useful, research findings must be disaggregated by sex. The scientific and medical communities, federal officials, and publishers should work together to ensure these goals are met. The study by Geller et al.44 in this issue reinforces the need for such a coordinated effort. © Mary Ann Liebert, Inc.
