Multivariate logistic regression analysisa of risk factors for treatment resistance (backward method)
| Variable | Odds ratio | 95% CI | p value |
|---|---|---|---|
| Use of two or more antibiotics | 3.47 | 1.21–9.95 | 0.020 |
| Vancomycin use | 5.64 | 1.11–28.52 | 0.036 |
| WBC count > 15 × 103/µL | 4.11 | 1.61–10.50 | 0.003 |
| More advanced CKD (eGFR < 30 mL/min/1.73 m2) | 2.83 | 1.00–7.94 | 0.048 |
CI, confidence interval; WBC, white blood cell; CKD, chronic kidney disease; eGFR, estimated glomerular filtration rate.
