Table 2 Blood glucose management, according to treatment group

From: Tight computerized versus conventional glucose control in the ICU: a randomized controlled trial

Management strategy TGC (n = 1,336) CGC (n = 1,312) p
Patients with BG data, n (%) 1,317 (98.6) 1,284 (97.9)  
Morning laboratory BG, mmol/L; median (IQR) 6.5 (5.9; 7.3) 6.9 (6.2; 7.9) <0.001
 Mean bedside BG, mmol/L; median (IQR) 6.4 (6.0; 7.1) 7.0 (6.3; 7.9) <0.001
  Standard deviation of bedside BG, mmol/L; median (IQR) 1.6 (1.2; 2.3) 1.6 (1.2; 2.2) 0.17
Minimal BG, mmol/L; median (IQR) 3.2 (2.6; 3.9) 3.9 (3.2; 4.8) <0.001
Interval between 2 measures, min; median (IQR) 139 (120; 161) 175 (141; 210) <0.001
Severe hypoglycemia, n (%)a 174/1,317 (13.2) 79/1,284 (6.2) <0.001
Moderate hypoglycemia, n (%)a 743/1,317 (56.4) 384/1,284 (29.9) <0.001
Treated with insulin, n (%)b 1,239/1,314 (94.3) 1,052/1,290 (81.6) <0.001
Daily insulin dose, IUc; median (IQR) 43.1 (24.5; 70.0) 34.1 (17.9; 58.3) <0.001
  1. Each statistic was computed on the non-missing value, i.e., the whole sample unless specifically indicated. SI conversion factors: to convert blood glucose levels from mmol/L to mg/dL: multiply by 18.01
  2. BG Blood glucose measured at bedside, IQR interquartile range
  3. aIncidences of severe and moderate hypoglycemia were calculated in the patient population for whom data with respect to blood glucose levels were available as the percentages of patients who experienced at least one episode of severe and moderate hypoglycemia (defined as BG ≤2.2 and ≤3.3 mmol/L, respectively)
  4. bThe numbers of patients for whom data with respect to insulin treatment were available are slightly different from the numbers of patients for whom data with respect to blood glucose levels were available
  5. cDaily insulin dose was calculated only for patients treated with insulin
