ATLAS - Cohort generation history

[SELVA_MUTHU_KUMARAN (Selva)]

Hello Everyone,

I would like to know whether it is possible to find the history of cohort generation.

Meaning, let’s say I have a cohort with Id 42 which is ran 3 times (each time with little modification in criteria)

Run 1 - 21 subjects

Run 2 - 23 subjects

Run 3 - 25 subjects

So I would like to know whether there is any option view to history of cohort runs (generation) or I have to make note of it at the end of each run?

In this example, it’s 3 runs but sometimes it could be 15 or 16 runs.

Will I able to view the history of runs that particular cohort had?

Cohort definitions does not currently support this, but cohort characterization does. Maybe you want to set up a characterization project with a simple deisgn (say, gender demographics) and that will give you the counts of people (as maile/female breakdown) and each time you run the cohort characterization, a snapshot of the cohort definitions is captured, so you can review the results from each execution of the characterization analysis.
