The authors did not observe significant correlations between serum galectin-3 and inflammatory markers (CRP, IL-6, ferritin, procalcitonin), anemia, coagulation abnormalities, or serum enzymes (alanine or aspartate transaminases, LDH, creatinine kinase), even though the results of these tests differed significantly between severe and non-severe patients [27]. Here, IL6 is linked to anemia (phenotype).
