Compared baseline radiological data in common versus severe
| Volume measurement | Common (n = 76) | Severe (n = 17) | P value* | ||
|---|---|---|---|---|---|
| Frequencya (%) | Volume (%) | Frequencya (%) | Volume (%) | ||
| Total lung | NA | 1.5 (0.2–5.4) | NA | 33.0 (22.5–37.0) | < 0.001 |
| Left upper lobe | 15.4 | 0 (0–0.4) | 5.8 | 2.0 (0–14.5) | 0.003 |
| Left lower lobe | 27.7 | 0.2 (0–0.6) | 17.6 | 1.0 (0–15.0) | 0.008 |
| Right upper lobe | 9.2 | 0 (0–0.3) | 35.4 | 4 (0–19.0) | 0.01 |
| Right middle lobe | 1.5 | 0 (0–0.1) | 0.0 | 0 (0–0) | 0.79 |
| Right lower lobe | 46.2 | 0.2 (0–1.5) | 41.2 | 10.0 (0–16.5) | 0.006 |
NA not applicable
aFrequency is calculated as the number of lobes including the main lesion at admission divided by the number of patients (76 in non-severe group and 17 in severe group)
*Nonparametric continuous variables were compared through Mann–Whitney U test for independent samples. P < 0.05 was considered statistically significant
