Parameter	HR	95% CI	P-value
NT-proBNP – RFO Groups:
Group 1		Reference
Group 2	1.12	0.56–2.21	0.75
Group 3	1.34	0.67–2.68	0.40
Group 4	1.83	1.02–3.54	0.04
Age [years]	1.04	1.02–1.06	< 0.001
Diabetes (0 – no, 1 – yes)	1.07	0.63–1.81	0.81
Gender (1 – male, 2 – female)	0.76	0.49–1.18	0.76
Severe NYHA Class (0 – Class 1 and 2, 1 – Class 3 and 4)	2.06	1.06–3.99	0.03
Hemoglobin [g/dl]	1.21	1.05–1.39	0.01
Log CRP [mg/dl]*	1.31	1.03–1.65	0.03
Log phosphorus [mg/dl]*	0.82	0.68–0.99	0.04
Log dialysis vintage [months]*	1.08	0.83–1.41	0.56

CRP – C-reactive protein, NT-proBNP – N-terminal pro-B-type natriuretic peptide, NYHA – New York Heart Association, RFO – relative fluid overload.

^*Hazard ratio for each increase in 1 SD in log of the variable.
