Not really, John:
Of course I did read the paper including 9 papers quoted by Gotzsche to make sure I grasp the context. Only afterwards did I post.
In doing so, I was thinking of the BEIR VII-2 committee which at least in 4 cases quoted (approvingly) 'momentous' radioepidemiological studies apparently only from reading the abstracts, where the text and/or the data do not sustain or rather contradict the claim made in the abstract.
Furthermore, ALL radioepidemiological studies are covered by Pubmed.
BTW: Regarding one of these studies, a member of the ICRP main commission remarked in a recent controversial 'public' discussion to me: "Forget about this study" (one which supported BEIR-VII and hence was distinctively endorsed by them) and regarding a more recent one (even more 'momentous'): "This one is even worse".
So, I have every reason to allege that the finding of Gotzsche pertains to radioepidemiological studies too - including those claiming to uphold the LNT postulate.

Thanks for point this article out. However, the list or database that the author cited, PubMeb, is primarily medical articles, not radiation biology. I assume that you would have understood this if you had read the article and not just the absract.
As I had posted in the past:
>From an article about physicians doing clinical
"It was just before an early morning meeting, and I was really trying to get to the bagels, but I couldn't help overhearing a conversation between one of my statistical colleagues and a surgeon.
Statistician: "Oh, so you have already calculated the P value?"
Surgeon: "Yes, I used multinomial logistic regression."
Statistician: "Really? How did you come up with that?"
Surgeon: "Well, I tried each analysis on the SPSS drop-down menus, and that was the one that gave the smallest P value"."

May we never confuse honest dissent with disloyal subversion.
