Predictive value of NLR, PLR, SII and CTII for OS of acral melanoma patients
| Indexes | Cut-off | AUC(95%CI) | Sensitivity | Specificity | Accuracy | P |
|---|---|---|---|---|---|---|
| NLR | 2.35 | 0.629(0.526-0.732) | 0.544 | 0.714 | 62.8 | 0.018 |
| PLR | 129 | 0.611(0.507-0.715) | 0.561 | 0.661 | 61.1 | 0.042 |
| SII | 615 | 0.655(0.553-0.757) | 0.632 | 0.679 | 65.5 | 0.004 |
| CTII | 0.08 | 0.68(0.58-0.78) | 0.877 | 0.482 | 63.7 | <0.001 |
NLR: neutrophil-lymphocyte ratio; PLR: platelet-lymphocyte ratio; SII: systemic immune-inflammation index; AUC: area under curve; CI: confidence interval; CTII: circulating T cell immune index.
