Table 2 Crude OR (95% CI) of factors associated with blood glucose concentrations < 80 mg/dl or ≥ 150 mg/dl

From: Which variables are associated with blood glucose levels outside the target range in surgical critically ill patients? A retrospective observational study

  1. BG = blood glucose; CI = confidence interval; IIT = intensive insulin therapy; MELD = model of end stage liver disease; OR = odds ratio; SAPS II = Simplified Acute Physiology Score; SOFA = Sequential Organ Failure Assessment.
  2. Number of data sets: see Table 1. ORs with p < 0.05 are highlighted in bold numbers.
  3. To convert the values for glucose to millimoles per litre, multiply by 0.05551.
  4. For comparison with the other types of surgery, the risk has been set at 1 for neurosurgery.
