Split thread That's a really great and very helpful document @JaimeS. I appreciate we probably can't have the document itself in our library, but could we include it as a linked reference in our Library thread (rather than just this library discussion thread)? And a question. In your document ... ... the authors state in their conclusion ... Could you give some insight what this is saying please to a non-medic, especially the second sentence. Sounds very significant, though I suppose it depends on how well peer reviewed the paper is.
