AW: [ RadSafe ] Significant results in abstracts

[John Jacobus]

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
