Due to serious data quality concerns, all data with PTIDs containing the format 381_S_10### have been removed from the ADNI data repository. ADNI leadership strongly advises that data with these PTIDs not be used in any data analysis, submission of abstracts, or publications. Furthermore, ADNI leadership requests that any abstracts or papers which have been submitted using this data be appropriately revised due to concerns with data quality. More information click here.
