| Sensitivity | Specificity | LR+ | LR- | AUC | |
| CRP ≥20 mg·L−1 | 74 (61–87) | 77 (63–92) | 3.3 (1.8–6) | 0.34 (0.20–0.55) | 0.81 (0.72–0.90) |
| sTREM-1 ≥80 pg·mL−1 | 62 (47–76) | 85 (73–97) | 4.1 (1.9–8.9) | 0.45 (0.31–0.65) | 0.83 (0.74–0.92) |
| PCT ≥0.25 ng·mL−1 | 25 (12–39) | 76 (60–91) | 1 (0.5–2.2) | 0.98 (0.77–1.26) | 0.52 (0.39–0.65) |
| LBP ≥7 μg·mL−1 | 79 (67–92) | 77 (63–92) | 3.5 (1.9–6.4) | 0.27 (0.15–0.48) | 0.83 (0.74–0.92) |
Data are presented as % (95% CI). LR+: likelihood ratio positive; LR-: likelihood ratio negative; AUC: area under curve; CRP: C-reactive protein; sTREM-1: soluble triggering receptor expressed on myeloid cells; PCT: procalcitonin; LPB: lipopolysaccharide-binding protein.
