From: Application of a population-based severity scoring system to individual patients results in frequent misclassification

Figure 2

Theoretical distributions of APACHE II scores with varying SDs. A set of theoretical distributions of reported APACHE II scores based on standard deviations of 6 and 12 (which were what we observed in the case scenario data.) For the purposes of comparison, a set of curves using an intermediate standard deviation of 9 is also shown. In every curve, the shaded area illustrates the theoretical probability of misclassification based on a cut-off score of ≥25.
