Figure 4. Association between IL-6 levels (pg/ml) with various biomarkers in the study population.

IL-6 correlations were assessed with (A) serum procalcitonin; (B) C-reactive protein; (C) serum fibrinogen; (D) serum D-dimer; (E) serum lactate dehydrogenase level; (F) serum ferritin; and (G) serum creatinine kinase levels.

Significant correlations were observed between IL-6 and serum procalcitonin, serum LDH, serum ferritin and serum creatinine kinase levels.
