Table 2. Determination of sophisticated cutoffs for the continues parameters associated with overall survival using “Youden” approach.
| Factors | Cut off | AUC for OS (95% CI) |
|---|---|---|
| PSA [ng/ml] | 58 | 0.737 (0.635–0.840) |
| LDH [U/l] | 229 | 0.761 (0.667–0.854) |
| NLR [Ratio] | 3.7 | 0.655 (0.552–0.757) |
Abbreviations: PSA: Prostate specific antigen; LDH: Lactate dehydrogenase; NLR: Neutrophil to lymphocyte ratio; AUC: Area under the curve; OS: Overall survival.
