FP and FN Cases of Phenotyping Algorithms.
| Patterns of cases | (A) | (B) | (C) | (D) | (E) | (D) | (G) | |
|---|---|---|---|---|---|---|---|---|
| FP | Temporary glycemia | 5 | 0 | 5 | 17 | 0 | 0 | 3 |
| Secondary DM | 5 | 0 | 1 | 0 | 0 | 0 | 2 | |
| T1DM | 2 | 1 | 0 | 1 | 0 | 1 | 0 | |
| Non-T2DM (except above cases) | 13 | 0 | 4 | 0 | 2 | 0 | 17 | |
| FN | Regarded as T1DM | 0 | 0 | 0 | 0 | 0 | 2 (one case overlaps case with T2DM and T1DM) | 4 |
| No E11x (T2DM) ICD-10 code | 1 | 11 | 1 | 0 | 1 | 3 | 2 | |
| Regarded as temporary hyperglycemia | 0 | 0 | 0 | 0 | 1 | 10 | 0 | |
| No abnormal lab owing to good control of T2DM | 0 | 3 | 0 | 4 | 1 | 4 | 3 | |
| No test of HbA1c and glycoalbumin | 0 | 2 | 0 | 0 | 0 | 1 | 1 | |
| No glucose test | 0 | 0 | 0 | 0 | 0 | 0 | 0 | |
| Treated with exercise or diet therapy | 0 | 14 | 0 | 0 | 0 | 5 | 0 | |
| No T2DM medication (treated in other hospitals) | 0 | 12 | 0 | 0 | 0 | 0 | 0 | |
| Others | 9 | 11 | 0 | 0 | 0 | 0 | 0 |
Some overlapping cases exist between patterns in FN cases of proposed algorithm (B). Nine FN cases of algorithms (A) or (B) were classified as non-T2DM by the rule in the first step.
