BAC BSI and SeptiFast in comparison to blood culture.
| blood culture | BAC BSI | SeptiFast | ||
|---|---|---|---|---|
| neg | pos | neg | pos | |
| neg | 122 | 29 | 140 | 11 |
| pos | 8 | 34 | 11 | 31 |
| ROC-AUC (95% CI) | 0.81 (0.75–0.86) | 0.83 (0.76–0.88) | ||
| % sensitivity (95% CI) | 81.0 (65.9–91.4) | 73.8 (58.0–86.1) | ||
| % specificity (95% CI) | 80.8 (73.6–86.7) | 92.7 (87.3–96.3) | ||
| % PPV (95% CI) | 54.0 (45.0–62.7) | 73.8 (60.8–83.7) | ||
| % NPV (95% CI) | 93.9 (89.0–96.6) | 92.7 (88.4–95.5) | ||
ROC-AUC = receiver operating characteristic-area under the curve; PPV = positive predictive value; NPV = negative predictive value; CI = confidence interval.
