I’m not sure the headline of this new piece at PJMedia is accurate given Dalrymple’s summary of the report in question:

There were so many exclusions that of the 51,085 men screened, only 790 met the criteria inclusion, and of those only 705 completed the trial. As the journal’s editorial that accompanied the paper pointed out, this in itself severely limited the applicability of its results: indeed, rendered them almost nugatory…

Seldom has so mountainous a trial given birth to so murine a result. The authors are not to be blamed for this, however: the whole purpose of research is to discover what was previously unknown and whether something will work cannot be known in advance.
