Accuracy of Point Scores Based on Logistic Regression Models for the Diagnosis of Acute Rhinosinusitis and Acute Bacterial Rhinosinusitis Using 3 Different Reference Standards
| Reference Standard | Score Points | Sinusitis/Total No. (%) | Likelihood Ratio |
|---|---|---|---|
| Abnormal CT finding | |||
| Low risk | −2 to 1 | 17/43 (39.5) | 0.29 |
| Moderate risk | 2 to 4 | 32/50 (64.0) | 0.80 |
| High risk | 5 to 9 | 69/78 (88.5) | 3.40 |
| Total | 118/171 (69.0) | ||
| Classified as low or high risk | 121/171 (70.8) | ||
| Abnormal antral puncture finding | |||
| Low risk | −2 to 0 | 11/44 (25.0) | 0.30 |
