Gender-, age and heart rate adjusted means (95 % CI) of ECG analysis parameters in healthy controls and dialysis patients

	Controls (N = 15)	Diabetic HD (N = 14)	Nondiabetic HD (N = 14)
Heart rate (/min)	65.37 (57.50–73.25)	79.89 (71.69–88.10)	78.79 (71.89–85.70)*
SDNNa (ms)	31.11 (22.53–42.96)	17.03 (12.34–23.49)	17.75 (13.55–23.25)*
pNN50 (%)	6.13 (0–12.57)	5.36 (0–11.78)	2.28 (0–7.67)
VLFa (s2 x10−3)	0.57 (0.30–1.08)	0.14 (0.07–0.27)*	0.20 (0.12–0.34)
LFa (s2 x10−3)	0.32 (0.13–0.76)	0.08 (0.03–0.19)	0.09 (0.04–0.18)
HFa (s2 x10−3)	0.27 (0.14–0.52)	0.10 (0.05–0.20)	0.07 (0.04–0.12)*
LF/HFa	1.19 (0.65–2.17)	0.76 (0.41–1.38)	1.27 (0.77–2.11)

* = p < 0.05 vs. controls; 95 % CI: 95 % Confidence Interval.

^aBecause of skewness of the distribution of the HRV parameters we calculated geometric means (± 95 % CI)
