Mean performance of all students on the differential diagnosis, diagnostic justification, investigations, and final diagnosis

Mean scores for building the differential diagnosis (Ddx), performing diagnostic justification (DxJ), ordering investigations, and identifying the correct diagnosis for all cases completed by all students. All scores are statistically different from each other (p < 0.001) with DxJ notably having the lowest score. The maximum score possible was 10 for each score. All scores are calculated independently from each other
