Table 4 Sensitivity, specificity, positive predictive value, and negative predictive value for selected cut-off values of the modified risk score in the Mongolian STEPS 2009 survey. 1018 men and women aged 35-64 years, of whom 59 had undiagnosed diabetes

From: Adapting existing diabetes risk scores for an Asian population: a risk score for detecting undiagnosed diabetes in the Mongolian population

  1. Sensitivity: Proportion who fulfill the cut-off criteria among those with undiagnosed diabetes
  2. Specificity: Proportion who do not fulfill the cut-off criteria among those without undiagnosed diabetes
  3. PPV: Positive predictive value: Proportion with undiagnosed diabetes among those who fulfill the cut-off criteria
  4. NPV: Negative predictive value: Proportion without undiagnosed diabetes among those who do not fulfill the cut-off criteria
  5. Cut-off point ≥ 9 most optimal according to the Youden-index
