Chest radiological features | SARS group (n = 16) | CAP group (n = 32) | Matched odds ratio | 95% CI |
---|---|---|---|---|
Results are expressed as number (%). | ||||
*OR and 95% CI for “air-space consolidation” versus “normal” plus “other features”. | ||||
†OR and 95% CI for “hyperinflation” versus “normal volume” plus “volume loss”. | ||||
All children in both clinical groups subsequently had abnormal chest radiographs. | ||||
