Maximal Glycemic Difference, the Possible Strongest Glycemic Variability Parameter to Predict Mortality in ICU Patients

Table 4

AUC of each glycemic variability parameter to predict ICU mortality.

Glycemic variability	Area under the curve (AUROC)	95% CI	value
Maximal blood glucose difference	0.69	0.64–0.75	—
Coefficient of variation	0.68	0.62–0.74	0.21
Standard deviation	0.67	0.61–0.73	0.005
J-index	0.63	0.57–0.70	0.006
