Cluster analysis for severity, mortality, and glucocorticoid status. a Disease severity and initial cytokine level. Higher admission IL-6, sIL2R, and CRP levels clustered into the severe and critical disease groups. b Mortality and initial cytokine level. When looking at mortality as outcome, there were no apparent signals with initial cytokine levels. c Mortality and mean cytokine level. Higher mean IL-6, sIL2R, IL-10, and D-dimer clustered with the death outcome. d Tocilizumab-treated patients, glucocorticoid status, and initial cytokine level. Patients who also received glucocorticoids had higher initial D-dimer, IL-6, and IL-10 levels
