Summary Estimates of Meta-Analysis for the Diagnostic Accuracy of Clinical Decision Rules that Diagnose (Rule in) CAP
| CDR Used to Diagnose CAP (Rule in) | Sensitivity (95% CI) | Specificity (95% CI) | LR+ (95% CI) | LR− (95% CI) | AUROCC |
|---|---|---|---|---|---|
| Any abnormal vital signs | 0.89 (0.79 to 0.94) | 0.49 (0.25 to 0.73) | 1.84 (1.25 to 3.03) | 0.24 (0.17 to 0.34) | 0.83 |
| Any abnormal signs or any abnormal pulmonary exam finding | 0.96 (0.92 to 0.98) | 0.43 (0.20 to 0.69) | 1.79 (1.22 to 3.01) | 0.10 (0.07 to 0.13) | 0.92 |
AUROCC, area under the receiver operating characteristic curve; CAP, community-acquired pneumonia; CDR, clinical decision rule; CI, confidential interval; LR, likelihood ratio.
