Table 3 Associations between plasma CNP and HRV parameters

From: Increased circulating bioactive C-type natriuretic peptide is associated with reduced heart rate variability in patients with chronic kidney disease

  Plasma CNP
ß 95% confidence interval p
SDNNa − 0.12 −0.19 – −0.04 0.003
RMSSDa − 0.11 −0.20 – −0.02 0.02
Triangular Indexa − 0.08 −0.14 – −0.03 0.004
LF/HFa 0.02 −0.08 – 0.13 0.65
  1. aThese parameters were logarithm transformed in the analysis due to their skewed distribution
  2. ß indicates per SD increment of CNP and was adjusted for age, sex, eGFR, diabetes mellitus, body mass index, current smoker, previous history of cardiovascular diseases, hemoglobin and systolic blood pressure
  3. Bold entries indicate statistical significance
