Characteristic | Predicted tympanic temperature, °C† | ||
---|---|---|---|
>37.5 | >38.0 | >38.5 | |
Cutaneous temperature threshold, °C‡ | 37.5 | 38.0 | 38.5 |
Sensitivity | 0.76 (0.69–0.82) | 0.82 (0.71–0.90) | 0.82 (0.67–0.91) |
Specificity | 0.65 (0.63–0.67) | 0.77 (0.76–0.79) | 0.90 (0.88–0.91) |
Positive predictive value | 0.16 (0.14–0.19) | 0.10 (0.08–0.13) | 0.13 (0.09–0.18) |
Negative predictive value | 0.97 (0.96–0.98) | 0.99 (0.99–1.00) | 1.00 (0.99–1.00) |
Accuracy | 0.66 (0.64–0.68) | 0.78 (0.76–0.79) | 0.90 (0.89–0.91) |
