Table 1.
Comparison of demographic and clinical features between patients with H1N1/H3N2 pneumonia and patients with SARS-CoV-2 pneumonia. Results are expressed as mean ± standard deviation for continuous variables and as absolute value with relative frequency for categorical variables. Abbreviation: ECMO = extracorporeal membrane oxygenation.
