Table 3 Sensitivity and specificity for the diagnosis of diabetes mellitus

From: Accuracy of a Novel Non-Invasive technology based EZSCAN system for the diagnosis of diabetes mellitus in Chinese

  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
  1. *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).
