Accuracy of selected clinical decision rules for pneumonia, pharyngitis, and acute rhinosinusitis
| Study | Sensitivity, % | Specificity, % | LR+ | LR− | DOR |
|---|---|---|---|---|---|
| CAP (adults)36 | 45 | 90 | 4.4 | 0.61 | 7.2 |
| Sinus Score for ARSa (adults)10 | 89 | 53 | 1.9 | 0.53 | 3.6 |
| Sinus Score for ABRSb (adults)10 | 78 | 63 | 2.1 | 0.35 | 5.9 |
| Strep (Centor) Score (adults)13 | 82 | 49 | 1.6 | 0.37 | 4.2 |
| Strep (Centor) Score (children)35 | 41 | 85 | 2.0 | 0.8 | 2.5 |
↵a Reference standard for ARS was abnormal CT.
↵b Reference standard for ABRS was antral fluid culture positive for a pathogen. ABRS = acute bacterial rhinosinusitis. ARS = acute rhinosinusitis. CAP = community-acquired pneumonia. DOR = diagnostic odds ratio (LR+/LR−). LR− = negative likelihood ratio. LR+ = positive likelihood ratio.
