Confounders
We undertook the following measures to mitigate possible effects of the confounders that might have influenced our study: we employed random assignment of students to cases and order, taking into account the possibility of a selection bias as some students of our faculty may have already had prior exposure to advanced technological systems and were more technically proficient than others and were hereby more interested in the topic of the tutorial and our study. However, we believe that technical proficiency does not help providing more accurate diagnoses. Although later versions of the CDSS may have potentially yielded improved results, there were no significant differences in diagnostic accuracy observed across different versions of the CDSS. Students who participated at a later date might have had knowledge of the cases due to their interactions with students who took part in the study at an earlier date. It is important to note that we explicitly instructed all students not to discuss the study with other interested students and never disclosed any diagnoses during the tutorials. Finally, it is possible that students who were in the later stages of their medical studies had a higher level of proficiency compared to students in earlier stages. However, our findings did not indicate any significant effect.
