Main biological parameters at admission including known prognostic markers and extension of SARS CoV-2 lesions on CT-scans are reported. Extension of lesions was classified into three groups (< 30%, 30–50%, > 50%). Missing values are indicated
Results are expressed as mean ± standard deviation (SD) or median [Inter Quartile Range] for quantitative variables, and comparability between groups was evaluated by Student’s T or non parametric Wilcoxon test (*). p value is indicated for each test (p < 0.05 was considered significant)
Results are expressed with number of patients/percentage for qualitative variables, and comparability between groups was evaluated by Pearson’s Chi-2 test with chi-2 > 3.84 considered significant
