Our Vision
The group aims to bring the well known results in the scientific literature into practice and attract attention to basic principles of randomization techniques including pro and cons of particular procedures. The Randomization Working Group is actively welcoming new members. If you are interested in joining or if you have further questions, please contact us. Hi guys
Which Randomization Methods Are Used Most Frequently in Clinical Trials?
In Summer 2022, the Randomization Working Group conducted an online survey on the current practices in the application of randomization in clinical trials. Of 145 unique respondents, 137 (94.5%) identified themselves as statisticians. Full Article: https://www.tandfonline.com/doi/abs/10.1080/19466315.2023.2225451
Better alternatives to permuted block randomization for clinical trials with unequal allocation
Meurer, Connor, and Glassberg published ‘Simulation of various randomization strategies for a clinical trial in sickle cell disease’, proposing a biased-coin adaptive randomization design for a trial with a small sample size of 45 and an unequal target allocation of 1:2 between placebo and active treatment, and compared it with the complete randomization and the permuted block randomization via computer simulation. The authors’ effort of seeking a better alternative to the inferior permuted block randomization is laudable, and the implementation of better randomization designs in trials is important.

Implementing Optimal Designs for Dose-Response Studies through Adaptive Randomization for a Small Population Group.
In dose-response studies with censored time-to-event outcomes, D-optimal designs depend on the true model parameters and the number of censored outcomes. In order to implement such a design in practice, an adaptive design that incorporates updated knowledge about the dose-response curve at interim analyses can be used [1]. Further, treatment allocation should involve randomization, which is essential to mitigate various experimental biases and perform valid statistical inference at the end of the trial. Here, we compare several randomization procedures and their impact on model estimation. Full Article: Implementing Optimal Designs
