Curation Notations:

Age at baseline and age at diagnosis were calculated in PPMI and BioFIND using date difference between date of birth (years) and informed consent date. There are 10 patients in PPMI without age because 3 participants do not have consent date, 6 participants do not have date of birth, and 1 participant does not have both. Age at baseline and age at diagnosis were calculated in PPMI and BioFIND using date difference between date of birth (years) and informed consent date.
