From: A new weighted injury severity scoring system: better predictive power for adult trauma mortality
Comparing specificity, positive predictive value (PPV), negative predictive value (NPV), and concordance against sensitivity for the weighted injury severity score (wISS) and the injury severity score (ISS), in the range of all severity (ISS 11–74), major (ISS 16–74), and critical (ISS = 25–74), test sample NTDB 2007–2014. The weighted ISS (solid line) showed better diagnostic attributes in the major trauma group, especially in critically injured patients comparing to the traditional ISS (dashed line)
