CT features and clinical stages.
| Characteristics | Mild stage | Moderate stage | Severe stage | Critically ill stage | P-value | Pearson correlation |
|---|---|---|---|---|---|---|
| Simple GGO | 12 | 6 | 3 | 1 | 0.031 | −0.969 |
| GGO with interlobular septal thickening | 7 | 6 | 12 | 4 | 0.886 | −0.114 |
| GGO with consolidation | 4 | 4 | 14 | 7 | 0.480 | 0.520 |
| Simple consolidation | 0 | 6 | 7 | 11 | 0.034 | 0.966 |
Data are expressesd as numbers.
If the patient's initial CT was negative, subsequent follow-up CT abnormalities were recorded. P-value associated with critically ill stage, Pearson correlation analysis.
CT: Computed tomography; GGO: Ground-glass opacity.
