Blood glucose variability and outcome

80 ≤ BG < 150 (mg/dl)	Total patients	Nonsurvivors (%)	OR (95% CI)	P value
always	118	4 (3.4%)	1.0	0.009
plus BG < 80	26	2 (7.7%)	2.4 (0.4; 13.7)
plus BG ≥ 150	450	45 (10.0%)	3.2 (1.1; 9.0)
plus BG < 80 and BG ≥ 150	210	33 (15.7%)	5.3 (1.8; 15.4)
	804	84 (10.5%)

BG = blood glucose; CI = confidence interval.

To convert the values for glucose to millimoles per litre, multiply by 0.05551.
