Block Size |
In a multicentre study subjects are randomly allocated to their study medication. Treatments are randomly organised in blocks so that an equal number of patients in each block will receive each of the treatments. The size of the block depends on the number of patients that each site is expected to recruit along with the number of treatment groups. For example, a 2 treatment group study with a block size of 4 could have blocks: AABB, ABAB, BABA, BBAA etc. Putting these together would give a randomisation schedule AABBABABBABA….. And therefore after every multiple of 4 subjects there will be an equal of subjects allocated to treatment A and treatment B. Randomisation schemes are made of randomly allocated blocks. |
