Table 2. Concordance of diabetes diagnostic criteria between the JDS and ADA using FPG and HbA1c.
| ADA Criteria | |||||||
| FPG diabetesa | HbA1c diabetesa | ||||||
| Non diabetes (N = 7,154) | Diabetes (N = 174) | K (P value) | Non diabetes (N = 7,153) | Diabetes (N = 175) | K (P value) | ||
| JDS Criteria | Non diabetes (N = 7,175) | 7,126 (99.3) | 49 (0.7) | 0.759 (<0.001) | 7,129 (99.4) | 46 (0.6) | 0.782 (<0.001) |
| Diabetes (N = 153) | 28 (18.3) | 125 (81.7) | 24 (15.7) | 129 (84.3) | |||
ADA, American Diabetes Association; FPG, fasting plasma glucose; HbA1c, hemoglobin A1c; JDS, Japan Diabetes Society; K, Kappa coefficient.
Data are expressed as number (percentage to the categories of the JDS criteria).
a
The kappa coefficients between the ADA-FPG and ADA-HbA1c criteria was 0.668 (P<0.001).
