Mean difference expressed as Mean (lower 95% CI, upper 95% CI). Variables determined to be significantly different (α < 0.05) between pre-intervention and post-intervention by a paired t-test are in bold and denoted by an asterisk (*). (bpm, beats per minute; HR, heart rate; h, hours; HRV, heart rate variability; ms, milliseconds; pre, preintervention; post, postintervention; rpm, respirations per minute; REM, rapid eye movement; RR, respiration rate).
