Cox-regression analysis for relation between admission and average glucose levels and all cause mortality.

	Univariate		Multivariate		Combined analysisa
1 mmol/l increase in	HR	95% CI	HR	95% CI	HR	95% CI
Admission glucose	1.10	1.08–1.13	1.10	1.07–1.13	1.07	1.04–1.10
Average glucose	1.17	1.10–1.23	1.22	1.14–1.30	1.11	1.03–1.20

HR: hazard ratio; CI: confidence interval.

Variables used for multivariate analysis: age, gender, admission diagnosis (acute coronary syndrome (ACS), cardiac arrest/heart failure/arrhythmia, others), diabetes, prior renal disease, prior heart failure, prior thrombotic event (cerebrovascular accident (CVA); transient ischemic attack (TIA);/ acute myocardial infarction (AMI)), atherosclerotic disease (peripheral, percutaneous coronary intervention (PCI)/ coronary artery bypass grafting (CABG), angina), duration of stay.

^aAnalysis including both the admission and average glucose into the regression model, thus the HR here represents the value of admission and average glucose independent of each other.
