The participants comprised 64 medical students and 14 residents. Medical students were fifth-year students who participated in a clinical clerkship at the Department of General Medicine, Chiba University Hospital, from May to December 2020. They were rotated in groups, each comprising about 10 students. Residents were in their first and second year and rotated through the same department during the same period. All students and residents were guaranteed that their evaluation would not be affected by their participation in the study.
