Note that this 2013-2018 CTSA comprises a new award (with a different grant number) from the 2008-2013 CTSA, due to a change in the NIH sponsoring center from NCRR to NCATS. Also note that due to NIH delays the period from 05/2013 to 09/2013 was funded by an extension of the prior award, but for consistency those funds are included in the first year amount reported here. |
