Some clinical trials get no respect.
There is something to be learned from every randomized clinical trial. However, because of physician bias and/or misinterpretation by the cardiovascular community and by the lay press, some trials seem to generate a lot of heat before they generate light. This is particularly true for trials comparing medical therapy to revascularization, (eg, PCI/stent or coronary artery bypass surgery).
