Table 1.
Patients’ characteristics at inclusion.
Fig 1.
BNP (A, C) and NT-proBNP (B, D) values according to the initiation of dialysis after 6 (A, B), and 12 months (C, D) follow-up.
The upper and lower limits represent the interquartile range (Q1-Q3) and the middle line of the box-plot represents the median. Differences between the groups were analyzed using the Mann-Whitney U test.
Table 2.
Relative risk for initiation of dialysis within 12 months follow-up.
Hazard ratios and 95% confidence intervals were calculated using univariate cox regression analysis.
Fig 2.
Kaplan Meier survival curves showing the association between survival and A) BNP above and below cut-off after 5 years follow-up. B) NT-proBNP above and below cut-off after 5 years follow-up. The difference between the groups was determined using the log-rank test.
Fig 3.
Kaplan Meier curves for survival without dialysis.
The population is stratified according to BNP concentration above and below cut-off, as well as creatinine above and below the median, after 5 years follow-up. The significance indicated represents overall comparison.
Fig 4.
Baseline plasma natriuretic peptide concentrations for BNP (A) and NT-proBNP (B), according to the urgent or programmed dialysis initiation.
Thirty patients had initiated dialysis within 5 years follow-up. Nineteen dialysis sessions were programmed and 11 were initiated urgently. Differences between the groups were analyzed using the Mann-Whitney U test.
Fig 5.
Kaplan-Meier survival analysis of BNP and NT-proBNP as associated factors with cardiovascular events.
A) Curves for baseline BNP concentration above and below the cut-off value 140 ng/L. B) Curves for baseline NT-proBNP concentration above and below the cut-off value 1345 ng/L. The difference between the groups was determined using the log-rank test.
