Yes, for the control group, we included basically the surgeries that women would have gotten prior to the recommendation that salpingectomy be included. Those were women who had hysterectomies alone, so their Fallopian tubes got left behind, or women who had tubal ligations, so their Fallopian tubes were tied rather than removed. That was our control group. There were 32,000 of them, and there were 15 cancers in that group.
Again, because these women are still quite young, this is not reflective of the number of cancers we expect to prevent. The average ages in these groups were 42 in the salpingectomy group and 41 in the other group, so we're nowhere near, with the follow-up that we have, the upward age of diagnosis of ovarian cancer. However, we've already seen the statistically significant difference in these groups at this very early stage, so that's very promising in terms of the risk reduction that we can expect.
