Table 3 Summary of task 3 results. Mean value (M) of the used time and mean value (M) of the mistakes made 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
