Variables were presented as means ± standard deviations (± SD), or numbers (percent %) depending on distribution. Involvement ≥ 50% was the cutoff for LUSI and antero-1-lateral LUSI, whereas involvement ≥ 65% was the cutoff for CTSI. Odds ratios with significant (p < 0.05) associations are indicated by *

CI confidence interval, CTSI chest computed tomography severity involvement index, ICU intensive care unit, LUSI lung ultrasound score involvement, OR odds ratio, P/F ratio between partial oxygen pressure and fraction of inspired oxygen, SOFA sequential organ failure assessment
