If you've seen any commercials for Entresto, (it's a medication used for heart failure), the Phase III trial that it used for FDA approval had a randomized group of over 8000 patients allotted to use either it or another drug called enalapril. The gulf in data between a trial that size and a collection of 60 blood donors without randomization could be measured in parsecs.
