^aBecause participants could “check all that apply,” the sum of all categories exceeds the number of accounts that participated (i.e., some participants selected multiple responses)
^bRecords include studies for which the organization was listed as the “lead sponsor” and the study was conducted in the USA; that is, we excluded records for which the principal investigator (PI) was the “lead sponsor,” and we excluded studies done outside the USA
^cTwo accounts selected both an “NCI cancer center” and an “Other cancer center”; thus, 97 accounts were affiliated with a cancer center
^d “Other schools” include: school of public health (N = 59, 16%), school of social work (N = 41, 11%), school of arts and sciences (N = 56, 15%), school of nursing (N = 72, 20%), school of dentistry (N = 40, 11%)
