Randomized controlled trial 1 article

randomized controlled trial denotes an experimental study design that randomly assigns participants to comparison groups with a specific role in clinical development and regulated biomedical research. A typical implementation combines random treatment allocation with parallel-group trial design, with control arm comparison shaping the resulting molecular, cellular or analytical outcome. Randomization defines the comparison design, whereas Phase I, II and III labels describe development stages and do not by themselves specify whether a study is randomized.
