Table 2.

Different biometric groups with respective number of patients.

Group	Number of patients	Awake sleep phase (min)^a	Light sleep phase (min)^b	Deep sleep phase (min)^c		Total sleep phase (min)^d
Higher HR^e (>80 beats/min)	50	65	232	128		425
Lower HR (<80 beats/min)	660	55	258	135		449
Higher RR^f (>20 respirations per minute)	0	—^g	—	—	—
Lower RR (<20 respirations per minute)	710	—	—	—	—
Higher HRV^h (>20ms)	683	—	—	—	—
Lower HRV (<20ms)	27	—	—	—	—

^aP=.02.

^bP=.001.

^cP=.1.

^dP=.006.

^eHR: heart rate.

^fRR: respiratory rate.

^gStatistical analysis was not performed to assess the differences between these groups because of the low number of patients in Higher RR and Lower HRV groups.

^hHRV: heart rate variability.
