All rapid responses
The authors should be congratulated for having done this study.
However, I am a bit concerned that a large number of studies might have
been missed. It is not possible to tell from the search and eligibility
I am mentioning our own studies because this is what I am best aware, but
I believe that several of them should have been included here. Please just
look in Pubmed under Guyatt G or Schunemann H and utility.
Below are three papers that spontaneously come to mind (I am not sending
this to enhance our citation but because I believe these - and probably
many other studies - should have been included). Guyatt and colleagues
published a number of other papers that possibly are relevant (and so do
the many other authors).
In summary a description of the review and selection critera a la
"systematic review" and PRISMA would be helpful. Perhaps there were clear
criteria for not including a great deal of the other existing literature.
I hope the authors find this information useful.
With kind regards,
