Public Deliverables

D7.8 – Validated virtual cohorts for in-silico trials

In this report we describe the metadata of the virtual cohorts that will be made publicly available here. In addition, we will specify the validation steps that have been taken to end up with these cohorts (level of validation). Furthermore, we demonstrate the feasibility of using of our virtual cohorts for in-silico trials via simple effect simulations. At the end, we will indicate under which conditions/constraints our cohorts may be used for other applications/use cases (disclaimer).

D4.6 – SOPs for validation of in silico models
