Multivariate relationship between ECE and vancomycin Ct valuesa
| Parameter | Mean B (SE) | Wald value | P value | OR | 95% CI of OR |
|---|---|---|---|---|---|
| Vancomycin Ct of ≤6.8 μg/mL | 2.894 (0.882) | 10.778 | 0.001* | 18.071* | 3.210–101.72 |
| Model constant | 1.190 (0.432) | 7.594 | 0.006 | 0.304 |
Logistic regression was done using the Wald forward method. Nagelkerke’s R2 value was 0.390. B, β coefficients; *, statistically significant differences.
