When a randomised, controlled clinical trial isn't one at all


The study used questionnaires filled in by people from a previously conducted clinical trial, but then subjected them to the usual meaningless epidemiological data dredging to look for correlations.
 
And then presumed, after falsely claiming to be a controlled clinical trial itself, to reach a finding about the management of blood sugars and type 2 diabetes that was the opposite of what the properly conducted earlier study had found!

Szwarc's comments about the dangers of data-dredging from long-since-closed trial are pertinent and worth reading but she strikes me as having an agenda that sometimes runs counter to common sense, and the inability to post feedback or criticism of any kind to what she posts concerns me.

She's almost certainly right this time, but I'd link to her with care.
