What does the RCT do?
A randomized controlled trial (RCT) is an experimental form of impact evaluation in which the population receiving the programme or policy intervention is chosen at random from the eligible population, and a control group is also chosen at random from the same eligible population.
What is RCT in pharmacy?
The randomized controlled trial (RCT) is regarded as one of the most valued research methodologies for examining the efficacy or effectiveness of interventions.
Why is an RCT the gold standard?
Randomized controlled trials According to the hierarchy of evidence for the evaluation of health care outcomes ( 9 )—the best way for seeking the truth are RCTs. They are considered as the gold standard because they deliver the highest level of evidence, due to their potential to limit all sorts of bias.
Why do we Randomise?
The basic benefits of randomization are as follows: it eliminates the selection bias, balances the groups with respect to many known and unknown confounding or prognostic variables, and forms the basis for statistical tests, a basis for an assumption of free statistical test of the equality of treatments.
How do you create a RCT?
The key components of design of an RCT are highlighted below.
- Random allocation. Each of the eligible participants should have an equal chance to be allocated the intervention or not.
- Allocation concealment.
- Blinding.
- Conduct.
- Outcome ascertainment.
- Sample size.
- Power of a study.
- Trial phases.
What makes a good RCT?
The quality of an RCT depends on an appropriate study question and study design, the prevention of systematic errors, and the use of proper analytical techniques. All of these aspects must be attended to in the planning, conductance, analysis, and reporting of RCTs. RCTs must also meet ethical and legal requirements.
How does RCT reduce bias?
The main appeal of the randomized controlled trial (RCT) in health care comes from its potential to reduce selection bias. Random allocation of the participants to different study groups increases the potential of a study to be free of allocation bias, but has no effect on other important biases.

What is a two arm RCT?
The RCT design most familiar to most people is probably the standard two-armed, parallel-design, individually randomized trial. The two arms in this case generally include the treatment arm and the control arm (alternative treatment/placebo arm).
