Figure 1. Linear association between plasma natriuretic peptides and cerebrovascular autoregulation.
The figure shows fitted restricted cubic splines and 95% CIs, indicating no evidence of non‐linear association between plasma natriuretic peptides (NTproBNP and NTproANP) and measures of cerebral autoregulation (phase and gain). All Pvalues are >0.05. dCA indicates dynamic cerebral autoregulation; NT‐proANP, N‐terminal pro atrial natriuretic peptide; and NT‐proBNP, N‐terminal pro brain natriuretic peptide.
