Ability of core temperature, prothrombin time, or D-dimer to predict heatstroke, based on receiver operating characteristic curves.
| Parameters | AUC | 95% CI | p value | Cut-off value | Sensitivity （%） | Specificity (%) |
|---|---|---|---|---|---|---|
| Core temperature (°C) | 0.723 | 0.661 − 0.786 | < 0.001 | 39.7 | 50.8 | 95.3 |
| PT (sec) | 0.721 | 0.664 − 0.779 | < 0.001 | 13.8 | 52.7 | 79.5 |
| D-dimer (μg/mL) | 0.724 | 0.666 − 0.782 | < 0.001 | 0.3 | 74.8 | 62.6 |
| Core temperature + PT + D-dimer | 0.802 | 0.750 − 0.855 | < 0.001 | 65.6 | 83.6 |
AUC: area under receiver operating characteristic curves; CI: confidence intervals; PT: prothrombin time.
