| APACHE II score on day 1 | 14 (12–17) | 18 (16–20) |
| SOFA score on day 1 | 4 (3–4) | 6 (4–8) |
| Haemoglobin concentration, g/L | 127 (20) | 129 (14) |
| Lymphocyte count, × 109/L | 0·74 (0·40) | 0·62 (0·37) |

Data are median (IQR) or mean (SD). COVID-19=novel coronavirus disease 2019. APACHE II=Acute Physiology and Chronic Health Evaluation II. FiO2=fraction of inspired oxygen. PaO2=partial pressure of oxygen. SARS-CoV-2=severe acute respiratory syndrome coronavirus 2. SOFA=Sequential Organ Failure Assessment.
