OAIC

MISSION STATEMENT:

The overall goal of the Pepper Study Registry (PSR) is to guarantee the proper and long term access to, preservation and management of data resources to be used for conducting future ancillary studies by investigators with an interest in aging-related research. The PSR provides meta-data for self-deposited aging studies from Pepper Older American Independence Centers (OAICs). The PSR also provides data resources to the Designated Community by curating, preserving, and disseminating raw data that are deposited into the repository.

PSR DATA INTEGRITY & AUTHENTICITY:

Describes the policy for data integrity and authenticity for the PSR. Data integrity and authenticity is managed within the PSR system as part of the processes for data deposit, database change management, and data access. The integrity and authenticity of the data also is recorded as part of the documentation of changes to the data.

PSR DATA PRESERVATION POLICY:

Describes the PSR's data preservation policy to the data depositors and users of the PSR. The PSR follows the general functions for data preservation described by the Open archival information system (OAIS) framework [1], including data ingest, storage, management, access, dissemination, and migration. The PSR recognizes the varying levels of responsibility in preserving each deposited item. Therefore, this policy of the PSR preservation plan is made available to all PSR staff and to the users of the PSR.

How to search: Enter any single word, or combination of words using " + " (space plus space) in between. As an example, to search for both male and female with a condttion of obesity that have DEXA, enter "DEXA + Obesity + M/F". Clicking a column header will sort the data by that column's data.
Notes: Most studies will have some available demographic and many will have laboratory data. An asterisks (*) indicate study collected by not available in the database.
