What do the authors mean by "strong evidence"?
It is my understanding that the jury is out on antidepressants. In other words, there is not even strong evidence for "On-Label" prescribing. 1
Therefore, I would like to understand what the authors mean by "strong evidence" (2) for off-label prescribing and how I can translate their understanding of strong evidence with, for example, a Cates diagram or absolute risk reduction numbers for patients.
In the interest of my patients, I would need to know for example on what kind of studies their "strong evidence" is based, what number and type of patients and how long did these studies run for?
Or is the "strong evidence" based on the DRUGDEX compendium, as indicated in table 1, if that is the case, that should be mentioned as conflict of interest? (3)
