	Sensitivity (%)	Specificity (%)
EZSCAN in all subjects (n = 195)*
EZSCAN diabetes index ≥ 40	85	64
EZSCAN diabetes index ≥ 50	67	72
EZSCAN diabetes index ≥ 60	60	78
EZSCAN in subgroup analysis (diabetes index ≥40 as threshold)
Men (n = 99)	82	65
Women (n = 96)	87	63
< 54 years (median age, n = 100)	61	83
≥54 years (median age, n = 95)	93	24
Comparison of 3 methods in patients who had an oral glucose tolerance test (n = 80)*
EZSCAN diabetes index ≥ 40	78	67
Fasting plasma glucose ≥ 7.0 mmol/L	44	100
Serum glycosylated haemoglobin ≥ 6.5%	56	93

*Diabetes mellitus was defined as a plasma glucose of at least 7.0 mmol/L fasting or 11.1 mmol/L at 2 hours post-load, or as the use of antidiabetic agents in all subjects (75 diabetic patients), and as a plasma glucose of at least 7.0 mmol/L fasting or 11.1 mmol/L at 2 hours post-load in patients who had an oral glucose tolerance test (9 diabetic patients).
