Blocked randomization with randomly selected block sizes.
Efird J. Efird J. Int J Environ Res Public Health. 2011 Jan;8(1):15-20. doi: 10.3390/ijerph8010015. Epub 2010 Dec 23. Int J Environ Res Public Health. 2011. PMID: 21318011 Free PMC article.
Selection and accidental bias may occur when participants are not assigned to study groups with equal probability. A simple random allocation scheme is a process by which each participant has equal likelihood of being assigned to treatment versus referent groups. .. …

Randomization and allocation concealment: a practical guide for researchers.
Doig GS, Simpson F. Doig GS, et al. J Crit Care. 2005 Jun;20(2):187-91; discussion 191-3. doi: 10.1016/j.jcrc.2005.04.005. J Crit Care. 2005. PMID: 16139163

Re-randomization tests in clinical trials.
Proschan MA, Dodd LE. Proschan MA, et al. Stat Med. 2019 May 30;38(12):2292-2302. doi: 10.1002/sim.8093. Epub 2019 Jan 22. Stat Med. 2019. PMID: 30672002 Review.
The treatment assignment vector and outcome vector become correlated whenever randomization probabilities depend on data correlated with outcomes. One straightforward analysis method is a re-randomization test that fixes outcome data and creates a reference distribu …
