Blind means the patient doesn't know if he's given active treatment or placebo. Double-blind means that the experimenter
doesn't know either. You label all the pillbox (momentary brainfart, I know that's not the real word) and a computer does the randomization. Triple blind means the statisticians don't know either. Quadruble blind studies haven't been performed yet, but just wait...
Oh, and all my support to Helio and Absol.
