  1. SD = standard deviation; TPN = total parenteral nutrition.
  2. ^Incomplete clinical details for a single patient, six patients (five adults and one child) had more than two risk factors present at once, which will explain why percentages do not add up to 100%.
  3. #the mean length of hospitalisation was calculated for each MC-CRBSI event in patients with multiple events.
