A–B. Nonlinear associations between systolic blood pressure, heart rate, and early mortality modelled using restricted cubic splines.

<p>The horizontal solid lines represent log odds = 0. The dotplots in the bottom represent density of observed values. A. Adjusted for heart rate and Glasgow coma scale. B. Adjusted för systolic blood pressure and Glasgow coma scale.</p
