Mean Likert scores for medical student responses to four questions about attitudes towards mental illness and type 2 diabetes mellitus (T2DM), asked at three different time points. A larger value corresponds with more stigmatizing attitudes. Error bars indicate standard error. T1 = baseline; T2 = following the intervention; T3 = following the course.
