Question special

Dr. Trivedi, Shoptaw, and co-authors. I would like to ask what is your opinion on the generalizability of the study results to a national, or even international population? Having been conducted at 8 different medical centers, I see that the study was geographically diverse. If I’m not mistaken, I believe it was mostly conducted at university medical centers. Would you expect similar results if extended to a private setting, or any other population at a national/international level?
