Curation Notations:

Education level in PPMI and BioFIND is a numeric variable (i.e., number of years of education). In PDBP and HBS, the variable is categorical (i.e., highest grade or level of school completed, or highest degree received.). The variable was harmonized between studies by using the number of years converted into four categorical values “0 years”, “Less than 12 years”, “12-16 years”, “Greater than 16 years”. Education level was aligned to number of years based on the average completion time for types of different degree levels available.
