We don't know how they gathered their data, do we? At least, the abstract
doesn't say how. If so, we're then hypothesizing, not unreasonably,
perhaps.
Hopefully, the full text of the study will explicitly state how they
determined caffeine intake.
As an aside I'm very frustrated (actually more than frustrated) by the fact
that the full text of many studies is not publicly available, specifically
when the study has been funded by public monies, e.g., grants. Not to
mention the more indirect public underwriting for many of the institutions
(e.g., universities) and personnel thereof.
I mean, we're not talking secrets of national defense here. In fact, the
opposite. That is, the intent is to publish the work and make it known.
Being a US citizen this probably wouldn't apply to this study, but it has
to many others.
I've twice emailed authors for study reprints, but never received them.
