Changes in mean performance for all students per completed case

The X axis shows completed cases 1 through 11 for both 1st year (11 cases) and 2nd year (10 cases) students; the Y axis shows the scores for each of: building the differential diagnosis (Ddx), diagnostic justification (DxJ), ordering investigations, and final diagnosis (Dx). Scores for DxJ increased by 40% (p < 0.001); no statistical changes were observed for the scores for Ddx, investigations, and final Dx across the cases
