OR (95% CI) of factors associated with blood glucose concentrations < 80 mg/dl or ≥ 150 mg/dl.
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.
Number of data sets: see Table 1.
To convert the values for glucose to millimoles per litre, multiply by 0.05551.
For comparison with the other types of surgery, the risk has been set at 1 for neurosurgery.
