Table 1.

Time comparisons for novices and experts during specific segment intervals and imaging planes used during the simulation. The analysis of preset to ready and ready to completion combined both sagittal and axial events.

Event Interval	Expert Average Time (s)	95% Confidence Interval	Novice Average Time (s)	95% Confidence Interval	$F$-statistic	Significance
Pretest to ready	20.48	18.137 to 22.822	44.11	38.540 to 49.684	54.741a	$p<0.05$
Ready to completion	17.76	15.328 to 20.189	30.57	24.797 to 36.346	14.978a	$p<0.05$
Axial image (ready to completion)	16.6	10.880 to 22.405	26.6	21.205 to 31.915	6.232b	$p=0.014$
Sagittal image (ready to completion)	19.99	11.842 to 28.141	38.6	31.021 to 46.168	10.693b	$p=0.001$
