People are "shocked" that a study about stents vs. open-heart surgery, which was funded by a stent company, withheld information that stents lead to more deaths. That's bad science, but there's nothing shocking about it. People like money. When you add money to science, you get business, not science. This is the norm. If you want science, you have to make sure that the people running a study have no stakes in the outcome either way. This is all but impossible in an industry largely controlled by health corporations, not doctors.
