The trial has been beset with controversy. The three areas of debate surround the definition of MI (or heart attack), the increased risk of death in the stent arm, and selective publishing of data. Here is the column: Latest EXCEL MI Analysis Settles Nothing; Flaws Remain You should study this one because it hints at how precarious medical evidence can be. On the This Week in Cardiology podcast, I discuss EXCEL, but also the issue of trust in science. This includes a few words on the matter of silly studies that still garner media attention. I’ve come to name these studies, howlers. One of the reasons behind this is the business model of medical publishing. Medical journals, like any media outlet, need attention. Coffee studies bring attention; statistics studies not so much. The pandemic has brought oodles of silly studies. A classic example is the broken study on cardiac MRI in recovered COVID patients. This one had to be corrected due to a slew of errors and now shows no concerning signal of cardiac harm from COVID.
