Median and IQR of inflammatory markers according to the blood eosinophils at the day of admission. In general, patients with a low relative eosinophil count showed a higher inflammatory markers as compared to patients with higher eosinophils (Mann-Whitney test for two groups comparisons, Kruskal-Wallis test with Dunn’s test for three groups comparisons). N = 417 for leukocytes and granulocytes, n = 156 for Procalcitonin, n = 406 for fibrinogen; * significant between < 100 and 100–300; # significant between < 100 and > 300; $ significant between 100 and 300 and > 300; § significant between < 2% and ≥ 2%
