Summary

Medical treatments areThe advent of electronic often dictated by authority, personal experience, and habit, but a 2-year-old collaboration of several thousand doctors and other researchers is working to change that. Known as the Cochrane Collaboration, the British-led effort is literally hand searching the world's literature to find and review all of the randomized control trials ever done—as many as a million of them.
