That's one hell of a serious accusation. Selectively publishing only successful trials is an outright fraud, and very likely a literally deadly one, at that. Do you have specific examples? Details, please - not on the "everyone knows" or "such and such quack webshite says" level. This is not to say that fraud doesn't happen or that it's effectively punished (hell, Andy Wakefield is still out of jail - the bastard has gotten away with merely losing his UK license and this fraud has lead to hundreds of dead bodies), but if some company has been caught at what you describe, I'd rather be aware of that. To stay away from any stuff they'd developed, if nothing else. Verifiable proof, please.
