  1. Bold: statistically significant
  2. *The log linearity was not respected for SOFA and age, and therefore, we created two qualitative variables.
  3. CRBSI: catheter-related bloodstream infection. OR: odds ratio. CI: confidence interval. IQR: interquartile range. ICU: intensive care unit. SOFA: Sequential Organ Failure Assessment. CVC: central venous catheter. AC: arterial catheter.
