Randomize into demography cohorts
Starting with the previous system update, you could create adaptive cohorts. And now with this system update, you can create demography cohorts.
Adaptive cohorts let you open treatment arms in a gradual manner to measure safety and efficacy as the study progresses. Demography cohorts, on the other hand, are similar to stratum groups: They let you create population groups according to demographic criteria, such as age. One advantage that demography cohorts provide that stratum groups don't is that you can set limits on each population group. Additionally, with demography cohorts, you can open and close each cohort based on the results obtained during the study conduct period. You can also adjust the limits for each population group throughout the study if you need to.
