TABLE 1.

The means (standard deviations) of the RMSE (unit: mm) for the femur and tibia shape reconstruction using 1, 2, and 3 image pairs by computer simulation. p values of a univariate analysis with a polynomial linear test are also given for the trend of reconstruction accuracy with increasing image pairs.

		1 image pair	2 image pairs	3 image pairs	$p$
Computer simulation	Femur	0.62 (0.075)	0.57 (0.088)	0.52 (0.09)	0.048*
	Tibia	0.72 (0.076)	0.67 (0.074)	0.63 (0.085)	0.049*

*: p< 0.05, significant linear trend.
