Results of multiple logistic regression of frequency domain heart rate variability indices associated with non-unplanned readmission in geriatric patients

HRV indices	Odds ratio	95% confident interval	p-value
Total power, ln(ms2)	1.39	1.04-2.00	0.046
LF power, ln(ms2)	1.22	1.03-1.49	0.032
HF power, ln(ms2)	1.27	1.02-1.64	0.046
LF/HF ratio	1.96	1.07-3.84	0.036

LF = low frequency; HF = high frequency

*All models were adjusted with age and length of hospitalization.

*P-values of Hosmer and Lemeshow Goodness-of-Fit Test: Total power = 0.622, LF = 0.078., HF = 0.727, and LF/HF ratio = 0.723.
