Prediction performance of the qSOFA scores and machine-learning models in the test set.
| Models | qSOFA Scores | qSOFA-Based Machine-Learning Models | |
|---|---|---|---|
| Outcomes | AUROC (95% CI) | p Value | |
| 3-day mortality | 0.78 (0.77–0.79) | 0.86 (0.85–0.87) | <0.001 |
| In-hospital mortality | 0.71 (0.69–0.72) | 0.75 (0.74–0.76) | 0.002 |
| 3-day ICU admission | 0.73 (0.72–0.75) | 0.79 (0.78–0.80) | <0.001 |
| ICU admission | 0.73 (0.72–0.75) | 0.79 (0.77–0.80) | <0.001 |
AUROC = area under the receiver operating characteristics; CI = confidence interval; qSOFA = quick Sepsis-related Organ Failure Assessment; ICU = intensive care unit.
