Restricted cubic spline depicting the continuous biomarker concentrations in relation to the risk of time to first AF recurrence. The continuous line indicates the central log relative hazard and the shaded area the 95% confidence intervals. P value for non-linearity: Total NT-proBNP, p = 0.362; NT-proBNP, p = 0.798; Ang2, p = 0.827 and BMP10, p = 0.364
