What is the advantage of Stork et al. (2013) choosing a Randomized Control Trial (RCT) design compared to a Controlled Trial without randomization? Randomization provides proof while absence of randomization provides support for clinical practice change. Only randomized control trials provide statistically significant outcomes from which practice can be improved. Randomization adds greater support for the outcome being a result of the intervention and not extraneous variables. Randomized control trials are experimental designs while control trials without randomization are descriptive designs
