Randomized Controlled studies are the golden standard of today. Companies that implement randomization in a clinical study are using expensive or external systems. Additionally, in some cases, companies are using paper-based methods. These systems and methods can prove to be troublesome and time-consuming. Moreover, these methods are not integrated as part of the workflow. So, we wanted to do something about it.

What is Randomization?

It is a method based on chance by which study participants are assigned to a treatment group. SMART-TRIAL uses randomized blocks with varied random block sizes. Block randomization works by randomizing participants within blocks so that there is an equal number of participants in each group.  

Why should I use this feature in my Clinical Study?

Block randomization has become a  commonly used technique in clinical trial design to reduce bias. Additionally, it creates balance in the allocation of participants to groups, especially when the sample size is small. It is simple to use, setup and it fulfills all the quality requirements that are relevant to this particular function. Additionally, by randomly assigning subjects to test groups and reducing bias, the study results are more reliable.

How does Randomization work in SMART-TRIAL?

To use this function you need to follow 3-4 simple steps.
1. You can simply specify that you want to create a clinical study using randomized functionality.
2. You need to specify the total number of subjects that you would like to recruit.
3. And finally, you indicate the names of the groups.

You can watch the short video below on how it works in SMART-TRIAL


In conclusion, Randomized Controlled studies have become the golden standard of today. It is a feature that can control and reduce bias in your clinical study. It can help with balancing out the participants into equal groups. Lastly and most important, it can help with the reliability of your results.
