Randomized Controlled Trials

Famous quotes containing the words controlled and/or trials:

    It does not follow, because our difficulties are stupendous, because there are some souls timorous enough to doubt the validity and effectiveness of our ideals and our system, that we must turn to a state controlled or state directed social or economic system in order to cure our troubles.
    Herbert Hoover (1874–1964)

    It is time to provide a smashing answer for those cynical men who say that a democracy cannot be honest, cannot be efficient.... We have in the darkest moments of our national trials retained our faith in our own ability to master our own destiny.
    Franklin D. Roosevelt (1882–1945)
