  1. CKD, chronic kidney disease; SBP, systolic blood pressure; CXR, chest x-ray; ICU; intensive care unit; AKI, acute kidney injury.
  2. aTachypnea defined by age-adjusted criteria: age 50 years, 25 breath/min; age >50 years, 30 breaths/min.
  3. bTachycardia defined by heart rate: 125 beats/min.
  4. cHypoxemia defined by age-adjusted criteria: age 50 years, oxygen saturation 93%; age >50 years, oxygen saturation 90%.
  5. dCompared by Exact Wilcoxon two-sample test.
