Data reported as median and interquartile range (IQR) or percentage. P values calculated with Kruskal-Wallis or chi-square tests, P for trend with ANOVA. P values < 0.05 are indicated in bold (PCT: procalcitonin; HRCT: high-resolution computed tomography; SARS-CoV-2: Severe Acute Respiratory Syndrome CoronaVirus-2).
