<"That, of course, exagerates the results.">
I agree...but there is an important distinction to be made here. Some forms of thrombosis are more sinister than others (wrt their implications). The biggest problem with the whole very late thrombosis issue is - when does the thrombosis risk end? Two years, three years....never? To my knowledge there is no data showing the risk tapering off. If that risk is going to be 1/2 of a percent per year for life (or at least for, say, a decade) - what then? No reduction in restenosis rate is worth that.
