Receiver operating characteristic curve analysis, showing the overall accuracies of the hematological-derived markers used to distinguish survival from non-survival dogs with acute pancreatitis.
| Parameter | AUC (95% CI) | P | Cutoff | Sensitivity (%) | Specificity (%) | Odd ratio (95% CI) | p-value |
|---|---|---|---|---|---|---|---|
| RDW (%) | 0.663 (0.540–0.786) | 0.015 | 18.85 | 42.4 (27.3–59.2) | 86.4 (72.8–93.9) | 4.66 (1.54–14.07) | 0.004 |
| Hemoglobin | 0.704 (0.583–0.812) | 0.001 | 11.3 | 52.3 (36.4–68.2) | 84.8 (72.7–97) | 6.13 (2–18.81) | < 0.001 |
| Albumin | 0.634 (0.506–0.757) | 0.045 | 2.6 | 59.1 (45.5–72.7) | 66.7 (51.5–81.8) | 2.89 (1.13–7.4) | 0.038 |
| HRR | 0.669 (0.547–0.790) | 0.012 | 0.66 | 50 (35.9–64.1) | 84.8 (68.5–93.7) | 5.6 (1.82–17.16) | 0.002 |
AUC, area under the receiver operating characteristic curve; RDW, red blood cell distribution width; HRR, hemoglobin-to-RDW ratio; RAR, RDW-to-albumin ratio.
p-values correspond to the chi-squared test. Mortality was associated with values above the cut-off for RDW and below the cut-off for hemoglobin, albumin, and HRR.
