NCTR

A Randomized Control Trial (RCT) is a trial in which participants are randomly allocated to one of two or more intervention arms allocating people to groups using a method based on chance (e.g., random number table, random computer-generated sequence, minimization, adaptive randomization). The control group is usually given either the standard intervention for the disease in question or a placebo while the other group (or groups) is assigned to the experimental arm(s) (drug or other intervention).

A Controlled Clinical Trials (CCT) is a trial in which participants are allocated to one of two or more intervention arms allocating people to groups using a method not based on chance (e.g., birthdate, day of the week registered, etc.). The control group is usually given either the standard intervention for the disease in question or a placebo while the other group (or groups) is assigned to the experimental arm(s) (drug or other intervention).
