Indeed, the process of peer review apparently is no failsafe barrier against sloppy work getting published. In all fairness, I must admit that scrutinizing a manuscript that is not 100% your speciality is a taxing job. So, I don't want to blame referees who did not invest the effort for thoroughly criticizing a manuscript, order and read all the references which they are not familiar with ... . How often is an important argument backed by a reference which you not happen to have on your shelf! My impression is that editors - where they get paid - should exercise more own judicious judgment and not just transmit the comments of the referees. If that would slow down the process of publishing - all the better!
Regarding one of your favourite incriminations, cherry-picking: It was the BEIR VII committee which did the picking of those epidemiological studies which at face value supported their view the best and to which they assigned outstanding importance. I just took their(!) cherries.
Regarding the body of relevant work - ATB survivors and nearly all therapeutic exposures are not relevant for assessing chronic exposures - I know of NO SINGLE paper which does support the LNT postulate (being compatible with is quite a different matter) but several ones who are incompatible with LNT.
Kind regards, Rainer

I was partly poking fun at you. Of course, there is
no way to determine if the radioepidemiology papers
you refer to were included in this PubMed sampling.
It appears that you are presenting two different
issues here. I am sure that you can find this effect,
e.g., abstracts that do not support the findings given
in the paper, even in your field of study.
As a separate issue, you, as a scientist, should
appreciate that one or two papers may not establish
the principal bases of a conclusion. It is the body
of work that counts. If you cherry-pick the data from
a few papers, you may miss the broad conclusions that
a greater number of studies support. As you noted in
the past, the Taiwanese study is not good one to base
the benefits or harm of radiation.
If the abstract does not reflect the content of the
study, then there is a problem with the peer review
process. And that is not a new issue either. See
