>That is a paper that you should not put your name on. I certainly would not. Their effects are also more like 0.11 not 0.15; the largest peak misrepresents all of the rest of the results.

Here are the paper's authors' affiliations:
Office of the Clinical Director, NIMH, Bethesda, Md. (Norman, Shaw); Section on Neurobehavioral and Clinical Research, Social and Behavioral Research Branch, National Human Genome Research Institute, NIH, Bethesda, Md. (Sudre, Price, Shaw).
It's hard for me to believe that the authors should not have put their name on this paper.

I do. But we live in a world where people write you letters for promotion, review your grants, etc. Using your own name to say these things in public is bad for your career. So I'd rather not.
Plenty has been said in scientific publications about how junk like this leads to most papers being false, how we shouldn't do statistics this way, etc. Scientists know, but it hasn't been communicated to the public yet.
That being said, the beauty of science is that you don't need to see my CV.
A basic understanding of what Cohen's d is, or a simple translation (with some heavy assumptions) into accuracy as I provided, is enough to see that the paper is total trash. They found nothing, but they found it at huge scale, so the p value was very small.
By no-op I mean that it contributes nothing and means nothing. It's a waste of time for everyone. In a world were bean-counting publications wasn't how science was measured, I'm sure the authors would never have considered even writing this up worthwhile, never mind submitting it.
The term comes from assembly which often has a no-op instruction https://en.wikipedia.org/wiki/NOP_(code) Something that does nothing (although, that nothing may be critical depending on the instruction set).
