| CXR Finding | Adjusted Relative Risk (95% CI)a |
|---|---|
|

| No antibiotics given in the ED | |
| Normal | Reference |
| Radiographic CAP | 6.07 (3.86, 9.54) |
| Equivocal | 3.67 (2.09, 6.44) |
| Atelectasis | 2.03 (1.09, 3.76) |
| Antibiotics given in the ED | |
| Normal | Reference |
| Radiographic CAP | 1.35 (1.06, 1.71) |
| Equivocal | 1.36 (1.06, 1.74) |
| Atelectasis | 1.13 (0.81, 1.56) |
