Let me take your question another way.
There are all kinds of ways to look at these issues. There are cross-sectional studies. There are longitudinal studies. The U.S. Army has done a very nice job of doing some of the surveys in theatre. We call them mental health advisory teams. Unfortunately, we didn't look for the use of mefloquine. We looked for barriers to care in depression and anxiety. For a lot of the time here, we really weren't using mefloquine—especially in Iraq. It was an oversight on our part.
I think that your epidemiologists and our epidemiologists would be happy to go back and flesh out the picture of how many people exactly get symptoms.
Back to the question about women, I'd love to see some longitudinal studies of female veterans—not just exposed to mefloquine, but all female veterans. There's a paucity of data there.
We could recommend some ways to get some more hard data.
