Here are five manuscript transgressions that make me hit "Reject" faster that you can blink. The first four in particular do not instill confidence in what you actually did in the study.1. Matched cohort masquerading as a case-controlThis happens quite a bit with papers submitted to third and fourth tier journals, but watch out for it anywhere. The authors claim to have done a matched case-control study, where there is indeed matching. However, the...

Botox and empathy: Less is more

While this is feasible when dealing with chemical reactions...

Medicine and the internet: Harnessing the yottabytes
What if medicine in the US is just like the internet?

And what takes time and skill is separating the two into...
