Note: p values correspond to statistical testing by class year using ANOVA for tests of means and Chi2 for tests of proportions so that significant values indicate that there was a difference between values in at least two classes. MS = Medical Student, with numbers corresponding to a year in the 4-year medical school curriculum they were completed at the time of the survey JHLES = Johns Hopkins Learning Environment Scale means correspond to a 1-5 Likert scale for each item IRI = Interpersonal Reactivity Index, a measure of empathy. Means are totals for 7 item subscales scored 1-5 for each item. The range could be 7-35.
