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.
