Blinding is not always feasible for RCT but should be implemented if possible. This process is conducted to minimize possible bias in implementation, dropouts, measurements, etc.

This process must be included in the experiment for the success of any RCT.īlinding refers to keeping trial participants, health care providers, assessors or data collectors unaware of the assigned intervention, so that they will not be influenced by that knowledge. Allocation concealment prevents researchers from influencing which participants are assigned to a given intervention group. This allows researchers to control all known and unknown factors that may affect results in treatment groups and control groups.Īllocation concealment is a technique used to prevent selection bias by concealing the allocation sequence from those assigning participants to intervention groups, until the moment of assignment.

Random allocation is a technique that chooses individuals for treatment groups and control groups entirely by chance with no regard to the will of researchers or patients' condition and preference. Randomized controlled trials (RCT) are known as the best method to prove causality in spite of various limitations.
