having a bit of a posting break over xmas, but this stuff is just
too comical to stay away. i think what they are trying to say
about 'single arm medical research' is just that it was not in
any sense a controlled trial. a controlled trial would have had
at least two arms to the research, one in which people were
trying to lose weight etc. *whilst using the onitor device*, then
comparing that to a parallel arm within which other people, drawn
from a theoretically similar population ( - preferably randomly
allocated to the different arms of the study - ) would have been
trying to lose weight etc. *not using an onitor* (e.g. perhaps just
having a nice thick rubber back round their chubby wrist instead?).
using a suitable twin arm design, it might be possible to tell whether
using an onitor actually made any difference to the participants ...
(providing sample size etc large enough for decent statistical power).
but without a second arm to the study, there is no way at all to tell
whether any weight loss etc. shown by those six women was anything
whatsoever to do with the sh*** onitor mock-up provided, or whether
they would have lost that weight anyway just because they were trying
to by other means. (the 'behavioral change techniques' identified are not
really anything to do with the onitor per se, simply a list of the different
sorts of strategies that plump women claim they try when they've decided
they would like to lose weight. (e.g. 'i'll eat my meals off a smaller plate'.)
it looks like a shockingly poor and shambolic piece of research, that ends
up with remarkably little that can actually be said that relates to using a
device such as an onitor. some possible reasons for the lengthy delay in
publishing the paper would include, (a) difficult to try to extract much
meaning from the feeble research data in the first place, (b) peer reviewers
in a scientific journal would have been asked to look over the paper, and
might well either have rejected the paper outright as very poor quality,
in which case it would have to be hawked round to rival journals, or
the reviewers might have demanded multiple revisions before they
finally agreed that the paper met a minimum standard for publication.
however, on the plus side, although 6 women might sound like a fairly
small sample, it sounds like they were actually quite large ladies, so ...?
