*
P value, VR vs CE training groups, Mann Whitney U test.
†
Upper confidence interval is an artificial construct as task completion time is capped at 300 s.
‡
P > 0.05 versus Pre-Training, Fisher's exact test.
§
P > 0.05 versus Pre-Training, Wilcoxon test for matched pairs. Data expressed as mean [95% CI].
