Participants (n = 130) were recruited from internal medicine and emergency medicine training programs and invited to participate in a simulation-based study evaluating a generative AI clinical decision support tool (GutGPT). After exclusions due to non-completion of the pre-survey or repeat participation, 108 unique individuals were randomized by group (2–5 participants per session) to either a standard AI dashboard (n = 56) or the GutGPT-enhanced dashboard (n = 52). Each group completed three UGIB scenarios in randomized order, followed by individual post-surveys and semi-structured interviews. The final analytic sample consisted of participants who completed both the simulation and the UTAUT post-survey (n = 106). All 106 participants also completed an individual semi-structured interview. Blue boxes represent participant flow and retention. Orange boxes denote participant exclusions. Gray ovals denote procedural steps (randomization and simulation).
