So again, we go on to another NIH trial and also a large trial from England called the CLASP trial, and one single center study out of Alabama of about 300 patients. The NICHD trial was purely low-risk patients. CLASP was kind of a classic Oxford study where somebody came to the doctor and the doctor said, "Holy cow, she needs aspirin!" and she got it. And another woman came and the doctors said, "This woman doesn't need aspirin" and she didn't get it. If a woman came to the doctor and the doctors said "Gee, I wonder if she needs aspirin," then she got randomized. So it ended up being about 75% of the women previously had preeclampsia. Neither of these very large studies showed any benefit to reduce the risk of preeclampsia. But the single center study in Alabama did show a reduction in the aspirin group of patients.
