Laboratory parameters collected on admission to the hospital of discharged and deceased COVID-19 patients are presented. Data are shown as % for categorical and as median (interquartile range) for continuous variables. Continuous data were compared using Mann–Whitney U test. Abbreviations: FiO2, fraction of inspired oxygen; hsCRP, high-sensitivity C-reactive protein; PaO2, partial pressure of oxygen; SpO2, peripheral oxygen saturation.
