The winds are changing. I saw an episode of Law and Order where the detectives were investigating a series of suicides at a university and traced it to trials of an antidepressant. They further found that the drug company had mounted a series of trials, but bad results vis-a-vis suicide had caused them to brush the previous trials under a rug. They continued to start new trials in the hope that one would be positive so they could publish it. So they arraigned the CEO of the pharmaceutical company for murder!
And only one day later I found an article in the Wall Street Journal: Antidepressants Under Scrutiny Over Efficacy. The subheading is even more heartening: Sweeping Overview Suggests Suppression of Negative Data Has Distorted View of Drugs.
The article addresses the very issue raised dramatically in the Law and Order episode -- the manipulation of multiple trials to showcase the ones that are positive and scuttle the ones that are negative.
