Figure 1.
Summary design of skin AF based IGT/diabetes detection decision model (SAF-DM), using SAF level age-dependent cutoff levels (shown here for age >50 years, different cut-off levels at lower age), using age percentiles.
Effects of low reflectance have not been included.

Figure 2.
Sensitivity and specificity of skin AF alone, skin AF based decision tree (SAF-DM), FPG, HbA1c and FINDRISC for correct classification of diabetes/IGT versus normal, using OGTT based WHO criteria, or for DM/suspicion DM using HbA1c based IEC 2009 criteria.
Table 2.
Diagnostic performance of skin autofluorescence alone (SAF), the skin autofluorescence based decision-tree (SAF-DM), FPG, HbA1c and FINDRISC score ≥10 points, compared to WHO-GTT defined diabetes-IGT, or IEC 2009 HbA1c-defined diabetes/suspicion.
