I bet this is not the only fake study out there eh. This is going to give a lot of fuel to Trump supporters and science skeptics.
Yes, I see lots of papers where the results are impossible (i.e., plots are inconsistent with reported data in tables, statistical test values are inconsistent with each other). Generally indicates faked data or incompetence.
In this case there was both. Even if wasn't based upon faked data the analysis had serious issues and should of never got through peer review. But proper review is hard: Yesterday I spent half a day reviewing a paper and it took a lot work find the critical flaws (and it is something that could have reasonable implications for public health). We also get no payment for peer review.
This is really not going to help the current situation. Only a few scientists are truely fraudulent. Many are incompetent though.
