Table 3 ROC analysis of differences between individual values for the prediction of 30-day poor outcomes. For each optimal cutoff value was calculated also a ratio as 100*(Dx-Dy)/Dx
Difference | Optimal cutoff | Sensitivity | Specificity | AUC | P |
|---|---|---|---|---|---|
D2-D1 | >5.3 mcg/L (> 31%) | 72.7% | 90.6% | 0.824 | P < 0.001 |
D3-D1 | > 7.1 mcg/L (> 42%) | 82.4% | 92.3% | 0.889 | P < 0.001 |
D4-D1 | > 4.0 mcg/L (> 24%) | 100.0% | 90.9% | 0.983 | P < 0.001 |
D3-D2 | > 2.1 mcg/L (> 11%) | 89.3% | 86.2% | 0.878 | P < 0.001 |
D4-D2 | > 11.5 mcg/L (> 63%) | 77.3% | 95.8% | 0.867 | P < 0.001 |
D4-D3 | > 3.8 mcg/L (> 26%) | 66.7% | 96.4% | 0.677 | P < 0.043 |
