E' stato stato davvero sconcertante per me osservare quanto riportato in alcuni lavori, ed in più osservare la grande quantità di lavori pubblicati in materia, con tatto di commenti da parte proprio di editori di riviste mediche altamente quotate. Ve ne propongo alcuni:

"… Andreas Lundh and colleagues analysed randomised controlled trials published in six high-impact general medical journals during two time periods a decade apart; they calculated the putative fall in IF that would have occurred had publication been denied to papers that were commercially sponsored [1].
Unsurprisingly, they found the expected association, since IF depends in turn on recent citation rates, and a body of literature shows that industry-sponsored trials attract more citations than those funded by a nonprofit source [2],[3]."

E ciò che più è impressionante è che ...
"...much of the scientific literature, perhaps half, may simply be untrue!
Afflicted by studies with small sample sizes, tiny effects, invalid exploratory analyses, and flagrant conflicts of interest, together with an obsession for pursuing fashionable trends of dubious importance, science has taken a turn towards darkness."
