Table 2. Serum CRP level: prognostic cutoffs calculation.
| Serum CRP level (test group, n=25) | AUC (%) | Calculated threshold value (mg/l) | Sensitivity (%) | Specificity (%) |
|---|---|---|---|---|
| CRP preop | 55 | 4.0 | 67 | 58 |
| CRP postop (POD1) | 73 | 39.8 | 80 | 72 |
| CRP discharge (POD5) | 88 | 23.2 | 86 | 72 |
| CRP increase (Postop−Preop) | 73 | 27.5 | 74 | 72 |
| CRP decrease (Postop−Discharge) | 42 | 21.9 | 60 | 72 |
ROC analysis is performed in a test group (n=25) of the study population to assess diagnostic accuracy of each perioperative measurement. Threshold values are calculated with relative sensibility and specificity as a prognostic marker for endoscopic recurrence in the test group.
