Multivariate-adjusted association between cTnI level and the hazard ratio of all-cause, cardiovascular, or non-cardiovascular death. In the multivariate restricted penalized spline model using variables selected by the Bayesian information criterion (BIC), the risk of all-cause, cardiovascular, and non-cardiovascular death showed a positive relationship to cTnI level. HR and 95% CI are shown using spline curves and shaded areas, respectively. The reference for HR was set to be 1.0 at the lowest cTnI level. The distribution of cTnI was plotted below the x-axis.
