...Which supports what I said, as only a small number of the studies listed as completed show the results, and even the ones that do don't show the raw data.
Interesting, this is more than I thought was required. But even still, it's much less than the amount of data the FDA actually gets. Not to mention that of the 1508 drugs the FDA has approved since 1940, this only useful for the 50 or so approved in the last couple years.
Also, the last time I heard phase IV trials didn't need to be registered at all, except for when they were required as a condition of approval.
