re the Diabetes Papers

>I dont have the original dat in front of me, but could it be the duration
of
followup, e.g was 10 years the mean follow up? The NNT might have been
based
on a survival curve analysis that would be different than using the total
number of events and the mean followup, since events occur at different
periods over the followup.

If this is the case then it stinks.
Ordinary GPs want quick information from papers. This method would suggest
that the basic info is not in the paper, _nor_ alluded to.
Curious that the NNTs we work out ourselves from the papers are not as good
as the NNTs that they quote in the papers. Why doesn't that surprise me?
