In fact (sorry, I'm in rant mode) it feels like medical trials need better regulation. I know that would be a big pain for the many scientists who are thoroughly professional and honourable, but something needs doing to stop the ones that are far from that. If a trial is well run (not saying perfect because nothing ever is) then no worries. But if blatant errors in methodology occur, then there should be some kind of remedy and/or sanction, because people's lives are at stake, literally. And if that puts off the deadbeats and charlatans from taking up science, good. It should also extend to any other complicit organisations, such as journals, especially those that blatantly flout their own ethical guidelines.
