Table 2 Summary of task 2 results. Mean value (M) of the used time and mean value (M) of the mistakes made (a = automatically measured and m = manually measured) for the 2D and 3D system as well as the corresponding mean difference (MD) between the two systems. Additionally the correlating P-values for the difference in time and mistakes of the Group A and B put together

From: A laparoscopic study investigating 3D vs 2D imaging systems using a pelvitrainer model with experts, non-experts, and students
