Dynamic Element Exclusions🔗
In contrast to static elements (e.g. participants, instruments, and instrument fields), which are fixed and consistently structured, dynamic elements refer to data that are programmatically derived, conditionally included, or vary based on participant behavior or system context. These elements may include calculated fields, system-generated metadata, or selectively captured measures such as biospecimens, geocoded data, and direct REDCap submissions. The following filters were applied to exclude specific dynamic elements from this release, based on participant status, visit timing, data completeness, and domain-specific conditions:
-
Participant Filters:
- No brain rating or brain rating noted “atypical” are not selected
- Only active participants and sessions are selected
- Visit Filters:
- Only visits whose 'LaunchPad Complete' Status was set to 'Complete' before July 1st, 2024 are included
-
Domain Filters:
- BioSpecimens
- Geocoding data
- Transition in Care
