FIGURE 1.

Absolute and relative numbers of neutrophils and CD62L expression on neutrophils in COVID‐19 patients and controls. (a–e) Absolute and relative numbers of mature and immature neutrophils, obtained by manual gating. (e, f) CD62L expression on neutrophils of healthy controls and COVID‐19 patients. Values are presented as a percentage of CD62L+ neutrophils. The colours in the heatmap (f) represent the median of the percentage of CD62L expression on neutrophils, varying from dark blue for lower expression to yellow for higher expression. Different letters indicate values that are significantly different from each other (P ≤ 0·05). Boxplot representation (centreline: median; box limits: upper and lower quartiles; whiskers: range). Differences were tested using the Kruskal–Wallis test with a post hoc Dunn–Bonferroni test
