Statistically significant. The categorical data are expressed as (%), and the continuous data are expressed as median (interquartile range (IQR): 25th, 75th percentile). HA: hospital admission; TCZ: tocilizumab; SpO2: oxygen saturation measured by pulse oximetry; CRP: C-reactive protein; ALT: alanine aminotransferase; AST: aspartate aminotransferase.
