Observed and predicted hospital mortality by the PANDORA score.

<p>Patients are grouped by decile-classes of predicted in-hospital mortality within 30 days after the cross-sectional survey derived from the PANDORA score for the development sample (left panel) from the years 2006–2009 (n = 43894) and the external validation sample (right panel) from the year 2012 (n = 12928). The numbers of patients in each decile (n) are given below the x-axis. Closed symbols (■) show observed mortality with 95% confidence intervals (CI) whereas open symbols (⦿) show predicted mortality. The PANDORA score has 7 indicator variables (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0127316#pone.0127316.t002" target="_blank">Table 2</a>).</p
