Notes:
Some PIs sponsored more than one protocol.
Since 1 protocol was not a clinical trial, total for analysis was one less than N for notify the PI and further testing.
Chi-Square analyses were only performed on Notify the PI and the set of All Withdrawal Stipulations Combined, and not performed on ‘Return for another visit’ or ‘Return for further testing’ because of small numbers.
