Can we believe the published results of studies sponsored by drug companies?

MinnPost: In a meta-study of drug company studies on non-steroidal anti-inflammatory drugs (NSAIDs), this was what an independent researcher found:

"[The analysis] found all the studies that had ever been published where one NSAID was compared to another. In every single trial, the sponsoring company’s drug was either equivalent to, or better than, the drug it was compared to: All the drugs were better than all the other drugs. Such a result is plainly impossible." [emphasis mine]

O, ye of little faith. Drug companies clearly hail from Lake Wobegon, where all the drugs are above average.
