Determinants of ΔHRV parameters of DM patients with age ≥65 years old.

ΔHRV parameters	Multivariate (stepwise)
	Unstandardized coefficient β (95% CI)	p
ΔLF
Systolic blood pressure (per 1 mmHg)	0.060 (0.009, 0.111)	0.023
Total cholesterol (per 1 mg/dL)	–0.146 (–0.173, –1.119)	<0.001
Hemoglobin (per 1 g/dL)	1.466 (0.822, 2.109)	<0.001
ΔHF %
Cerebrovascular disease	12.762 (0.216, 25.309)	0.047
Systolic blood pressure (per 1 mmHg)	0.357 (0.090, 0.625)	0.012
Fasting glucose (per 1 mg/dL)	–0.126 (–0.204, –0.048)	0.003

Covariates in the multivariate model included age, sex, duration of dialysis, a history of smoking, hypertension, coronary artery disease and cerebrovascular disease, systolic and diastolic blood pressure, albumin, fasting glucose, triglycerides, total cholesterol, LDL-cholesterol, hemoglobin, creatinine, potassium, total calcium, phosphorous, calcium-phosphorous product, iPTH, uric acid, Kt/V, ultrafiltration rate, and medications use including ACEI and/or ARB, Beta-blocker and calcium channel blocker.
