Question Posted 11/02/15:

How do I differentiate participants that have been included in ADNI 1 and are now in the follow-up in ADNI go vs the newly included participants ? Are the follow-up subjects continued from adni1 marked as screening or baseline for GO or do they have another designation ?

Thank you

There may be a more precise way to make the determination, so this may be a question for the clinical or data core, but all subjects enrolled in ADNI1 have a subject ID of 1-1999 and subjects enrolled in ADNIGO and ADNI2 have an ID of 2000 and greater.
