Evaluation of CC quality for kneeling and standing position settings.

	Position settings during CC
	Kneeling (n = 152)	Standing (n = 130)	P-value
Correct rate (%)	30.60 ± 27.42	24.73 ± 25.32	0.068
Pause happening (%)	11.18 ± 31.62	53.85 ± 50.04	<0.001
Depth (mm)	50.70 ± 7.12	53.18 ± 10.48	0.019
Frequency (times/min)	113.28 ± 10.44	114.09 ± 8.63	0.483
Over-depth rate (%)	16.89 ± 24.96	29.51 ± 35.03	<0.001
Less-depth rate (%)	39.01 ± 34.56	37.04 ± 36.10	0.641
Over-speed rate (%)	22.76 ± 30.30	23.96 ± 31.96	0.748
Less-speed rate (%)	18.02 ± 30.37	6.55 ± 17.86	<0.001

Note. All values were estimated with means (and with S.D. followed after “±”). P-values were offered to tell the differences between the kneeling and standing position settings.
