  1. CTSA Accounts affiliated with a Clinical and Translational Science Award (CTSA). The number of CTSA affiliated accounts exceeds the number of CTSAs because multiple accounts were sometimes affiliated with the same CTSA. Not CTSA Accounts not affiliated with a CTSA. Cancer center Accounts affiliated with a National Cancer Institute (NCI) cancer center or another cancer center. Not cancer center Accounts not affiliated with an NCI or other cancer center. ≥ 100 records Accounts with 100 or more registered studies in the USA for which the organization was listed as the “lead sponsor.” 20–99 records Accounts with between 20 and 99 registered studies. < 20 records Accounts with fewer than 20 registered studies
  2. aTwo accounts did not report whether they are affiliated with a cancer center; they are not included in this subgroup analysis
  3. bResults are for accounts that responded to this question. In our initial analysis, we found potentially invalid data; for example, some participants entered “0.5” rather than “50%”. This occurred because a software bug prevented us from enforcing a data validation rule in the survey. To verify these results, we emailed administrators who indicated that staff spent ≤ 1% of their time on trial registration and reporting. Post hoc, we excluded two outliers because they appeared to report the total number of staff employed at the organization rather than the number of staff who support trial registration and results reporting
