MPO levels were also different between SOFA 0–6 and SOFA ≥ 13 (median [10th–90th percentile]: 187.7 [53.9–665.2] ng/mL versus 2269.2 [229.7–5540.1] ng/mL, p = 0.0193) and SOFA 7–9 and SOFA ≥ 13 (median [10th–90th percentile]: 217.0 [76.0–4365.3] ng/mL versus 2269.2 [229.7–5540.1], p = 0.0332) in septic shock patients (Figure 4). Here, MPO is linked to septic shock.
