Atlas: Use of measurements with increments within the inclusion criteria

Hello all!

Im trying to define a cohort and I need to define an inclusion criteria that involves an increment between two or more measurements. Let me show an example:

  • Patients with an increment of PSA after 4 weeks where the last measurement is at least 50% greater than the first.

Using nested criteria I could associate the time between the two measurements but I can´t figure out how to do it with the increment.

Has anyone experience with something like this?
