  • Information is shown for three types of requests. Data requests are reviewed administratively. Requests for samples for ancillary studies to ongoing parent studies are submitted by the parent study and are approved once all the paperwork is in place and a sample list has been finalized by the parent study. External requests are submitted following a favorable peer review of an application for access and are approved once all the paperwork is in place and a sample list has been finalized by the Central Repositories. Very few requests for renewable samples (DNA from cell lines) have been received, so information for those requests is not shown.
