χ² for proportions in patients with sepsis and septic shock and negative at SIRS criteria (SIRS < 2) and qSOFA < 2: SOFA, PCT and MR-proADM comparison.

Patients with sepsis SIRS < 2 + qSOFA < 2 (n = 35)	SOFA ≥ 2 (54%)	PCT ≥ 0.5 ng/mL (57%)	MR-proADM ≥ 1 nmol/L (89%)
SOFA ≥ 2 (54%)	–	p = 0.80	p = 0.001
PCT ≥ 0.5 ng/mL (57%)	p = 0.80	–	p = 0.002
MR-proADM ≥ 1 nmol/L (89%)	p = 0.001	p = 0.002	–

Patients with septic shock SIRS < 2 + qSOFA < 2 (n = 10)	SOFA > 2 (80%)	PCT ≥ 0.5 ng/mL(60%)	MR-proADM ≥ 1 nmol/L (100%)
SOFA ≥ 2 (80%)	–	p = 0.34	p = 0.14
PCT ≥ 0.5 ng/mL (60%)	p = 0.40	–	p = 0.03
MR-proADM ≥ 1 nmol/L (100%)	p = 0.34	p = 0.03	–
