Table 2 Model performance: anatomic injury models

From: IMP-ICDX: an injury mortality prediction based on ICD-10-CM codes

Model description AUC (95% CI) H-L stat (95% CI) AIC
ISS 0.853 (0.846–0.860) 252 (191–310) 27,655
Single worst injury 0.886 (0.881–0.892) 92 (53–128) 23,289
IMP-ICDX 0.893 (0.887–0.898) 68 (36–98) 23,024
  1. The IMP-ICDX demonstrated the best discrimination, calibration, and AIC compared to the single worst injury and ISS models
