From: The impact of early hypoglycemia and blood glucose variability on outcome in critical illness

Blood glucose category
(mmol/L)
ICU mortality
Adjusted OR§ (95% CI)
Hospital mortality
Adjusted OR (95% CI)
<2.0 4.8 (3.3 to 7.0) 3.8 (2.6 to 5.6)
2.1–2.4 2.4 (1.6 to 3.6) 2.1 (1.4 to 3.1)
2.5–2.9 1.9 (1.4 to 2.6) 1.7 (1.3 to 2.4)
3.0–3.4 2.0 (1.5 to 2.5) 1.8 (1.4 to 2.3)
3.5–3.9 1.3 (1.0 to 1.6) 1.3 (1.0 to 1.6)
4.0–4.4 1.0 (0.8 to 1.2) 1.0 (0.8 to 1.2)
≥ 4.5 1.0 1.0
  1. APACHE = Acute Physiology and Chronic Health Evaluation; AuROC = area under the receiver operator characteristic curve; CI = confidence interval; ICU = intensive care unit; OR = odds ratio.
  2. ¶ Reference variable
  3. § Goodness-of-fit, P = 1.0; AuROC 0.85.
  4. ‡ Goodness-of-fit, P = 1.0; AuROC 0.82.
  5. §‡ Covariate adjustment for age, sex, surgical status, primary diagnosis, co-morbid illness, non-age-related APACHE II score, mechanical ventilation, acute kidney injury, year, and hospital site.
  6. For conversion of blood glucose from SI to conventional units divide by 0.05551.
