Currently the 2015 screening sessions (study == "Screening PD") are treated as normal sessions, but this gives two unexpected results:
- Only ≈5 cognitive tests are performed, but this is still flagged as
full_assessment == TRUE.
- For these subjects,
global_z_baseline is therefore based on this small set of tests (rather than on the full session which typically happens shortly after). This is not necessarily a problem, though it might be useful to have a per session metric e.g. global_z_total_tests to make it more explicit that this might be different to other cohorts.
