Curation Notations:

  1. Subject ID in harmonized AMP PD dataset was named participant_id. 
  2. “PATNO” was used as a participant_id in PPMI and BioFIND starting with “prefixes” PP- and BF- respectively (e.g., PP-3400, BF-1006, etc.).
  3. “GUID” was used as a participant_id in PDBP and HBS because there is no other subject ID starting with prefixes PD- and HB- respectively (e.g., PD-PDFK955YBE, HB-PD_INVKT000XM6, etc.).
