I would have thought that "we need more data" would qualify as a
conclusion. :)

Of course, I do not know for sure which paper Frank has in mind, but
google and google schoar readily come up with papers/editorials that
have a nearly identical title:

http://www.bmj.com/cgi/content/full/311/7003/485
http://bmj.bmjjournals.com/cgi/content/full/328/7438/476
(see also

http://www.ncbi.nlm.nih.gov/pubmed/6829975

My money is on Frank having the first of these publications in mind.

Cheers,

	Berwin
