Performance of 3 computer-aided National Early Warning Score models in predicting the risk of sepsis in the development and validation data sets
| Model | Discrimination C statistic (95% CI) | Calibration slope (95% CI) | |
|---|---|---|---|
| Development data set, YH | Validation data set, NH | Validation data set, NH | |
| M0: eNEWS only | 0.705 (0.692–0.719) | 0.708 (0.698–0.718) | 1.18 (1.12–1.23) |
| M1: M0 + age + sex | 0.763 (0.752–0.774) | 0.777 (0.769–0.784) | 1.18 (1.13–1.23) |
| M2: M1 + subcomponents of NEWS + diastolic blood pressure | 0.777 (0.766–0.787) | 0.791 (0.783–0.798) | 1.15 (1.11–1.18) |
