Overview of the Sensitivity, Specificity, PPV, NPV as well as likelihood ratio’s for FRL-F, %FRL-V, and sFRL in the Prediction of Postoperative Liver Failure
| Outcome parameter | FRL-F | %FRL-V | sFRL |
|---|---|---|---|
| Cutoff value | 2.69%/min/m2 | Normal liver <30% | Normal liver <30% |
| Compromised liver <40% | Compromised liver <40% | ||
| Sensitivity | 89% | 78% | 67% |
| Specificity | 87% | 80% | 87% |
| PPV | 57% | 44% | 50% |
| NPV | 98% | 95% | 93% |
| LR+ | 6.8 | 4.0 | 5.1 |
| LR− | 0.12 | 0.19 | 0.38 |
FRL future remnant liver, FRL-Volperc future remnant liver/total liver volume percentage, PPV positive predictive value, NPV negative predictive value, LR+ likelihood ratio for positive test result, LR− likelihood ratio for negative test result
