It is fantastic! I recently set up our randomized control trial using “randomize.net.” Following the menus on the website to prepare the clinical trial for randomization was very easy and failsafe. I have had to instruct research personnel on the use of this program and training has been accomplished successfully with one brief session. This program receives my highest recommendation.
