Table 2

Mean, standard deviation, and values of the COP feature MVAP for the larger and smaller halves of the IPVI feature values.

Age group	IPVI values		values
	The larger half	The smaller half
Younger	6.06 ± 0.70	4.84 ± 0.83	2.25 × 10^−3
Older	8.87 ± 1.55	5.78 ± 1.00	1.00 × 10^−5

Values of the features are mean ± standard deviation. Unit of MV_AP is mm/s.
