At a Glance
| Category | Detail |
|---|
| Condition | Pulmonary Nodules |
| Key Mechanisms | Computed Tomography (CT) imaging |

Key Highlights
- Pooled sensitivity of CT: 0.90 (95% CI: 0.89 to 0.91)
- Pooled specificity of CT: 0.74 (95% CI: 0.72 to 0.76)
- Positive likelihood ratio: 3.28 (95% CI: 2.81 to 3.83)
- Negative likelihood ratio: 0.13 (95% CI: 0.10 to 0.17)
- Diagnostic odds ratio: 33.20 (95% CI: 23.52 to 46.87)
Guideline-Based Recommendations
