What is RCT?

Randomized Control Trial (RCT) is an experimental technique that uses random assignment to facilitate fair comparison between treatment and no treatment groups.

It helps to ensure that any differences between and within the groups are not systematic at the outset of the trial.

Randomised Controlled Trials are considered to be a golden standard in social, health and other fields of research. More>>

Our service

TrialWiz.org conducts Randomised Controlled Trials of any type and in any field, based on its experience and strong technological platform .

We stress on design, proven standards and utilise advanced technology to maximise efficiency and minimise costs.

ResearchTool.org can help you develop RCT strategy, perform field work, validate results and conducts analysis.

About Us

TrialWiz.org is a team of experts in experimental design and IT, providing professional consulting and fulfilment services for Ransomised Controlled Trial experiments.

We have been working with leading universities and law enforcement organisations, amongst others.

We are continuously improving our platform,  making each consecutive experiment smoother and more efficient.


RCTs are considered by most to be the most reliable form of scientific evidence in the hierarchy of evidence that influences healthcare policy and practice because RCTs reduce spurious causality and bias.

Randomized Control Trials are extremely valuable in healthcare and clinical trials, but also in public and social policy, international development, criminology education and other fields.

Many major scientific organisations are considering RCTs or systematic reviews of RCTs to be the highest-quality evidence available.

The paper “Test, Learn, Adapt: Deveoping Public Policy with the Randomised Controlled Trials” published by the Cabinet Office, states that “Randomised controlled trials (RCTs) are the best way of determining whether a policy is working.”

Study Design

Randomised Trials can have many study designs, including Parallel-Group, Crossover, Cluster, Factorial. Most trials use parallel group design,  where each participant is randomly assigned to a group, and all the participants in the group receive or do not receive an intervention.

Correct design is the key to the successful RCT, and includes the choice of randomisation option, optimal number of subjects and groups, distribution criteria, concealment / blinding options, etc.

The flowchart on the right explains the process of a standard Parallel Group design.

Case study

Institute of Criminology (IOC) at Cambridge University was developing a complex research design project, incorporating multipage form, eligibility criteria, automatic submission notifications and many dependancies.

Initially the system was being developed in-house, but due to the complex requirements it ran into difficulties.

Commissioning TrialWiz.org allowed researchers to focus on the design, rather than development.

Using our experience with random assignment experiments we helped IOC to achieve results in the most efficient way.

The system allowed researchers to access results online at any time and from any computer, with downloadable files for analysis.

Cloud system

We have created an easy to use online ransom assignment tool for experiment and trial creation. It eliminates the need for programming and development, reducing costs and increasing turnaround.

Currently it’s in a beta testing stage and you are welcome to use it. Your feedback will help make this system better and add more useful features.
