Previously, we had treated NIH supplements with the same suffix, but different support years as the same “subgrant”. Today, we made a change to treat them separately. For example, previously U24TR001608-06S1 and U24TR001608-07S1, which both appeared in the TAGGS PDF of terminated grants and were later removed, were listed as a single row in the data for subgrant_id “S1”. Now, these each have their own row—one for subgrant 06S1 and one for 07S1.

As a result of this change, three reinstated supplements were added to our NIH data.
