Some clinical trial results not published

In a recent article in the UK's The Guardian, they divulge that in a recent study involving 90 drugs from 1998 to 2000, 43% of the drugs never had a report published on the results of their clinical trials. Reports are typically published within five years of a drugs release date to give doctors and patients critical information so they can make the right decisions when it comes to prescribing and taking the drugs.

The study performed showed that results from 909 different clinical trials did not have their results published. Also noted was the fact that typically those trials with more statistically significant results were published more often than those with non-significant results.

What do you think about this? Those conducting and participating in clinical trials have the right to have their undertaking shared with those who are about to take the drugs they're testing. Do you think this will change anytime in the future?
