^a Study phase: Clinical trials of biomedical interventions typically proceed through four phases - 1, Phase I; 2, Phase II; 3, Phase III; 4, Phase IIII
^b Participants who selected ‘multi-site’ in the survey were asked if the study was part of an international study. Those who selected ‘single-site’ did not due to question branching logic
