In 2002, an independent study on hormone replacement therapy was halted, because the drugs were strongly linked to an "increased risk for breast cancer, heart disease, stroke and blood clots" in women. The same year, the University of Wisconsin-Madison began offering an online course, "funded entirely by a $12 million grant from Wyeth Pharmaceuticals," that "promoted hormone therapy, touted its benefits and downplayed its risks." Wyeth makes two hormone therapy drugs, Prempro and Premarin.
