In the late (Day 3+) but not early stage of disease, both sMR and sPD‐L1 concentrations were higher in patients with infection compared to those without (respectively p= .006, AUROC = .65, CI .54–.76; p = .041, AUROC = .60, CI .51–.69) (Figure 3E,F; Figure S13E,F). This evidence concerns the gene SPDL1 and infection.
