|---|---|---|---|---|---|---|---|
| n = 88 | n = 155 | n = 36 | n = 69 | n = 39 | n = 26 | n = 105 | |

a
Note that the NGT group had HbA1c ≥ 5.8% (40 mmol/mol) in the screening step of the standard algorithm and will therefore be regarded as having prediabetes.
b
Low risk, defined as having RPG < 6.1 mmol/L & HbA1c < 5.8% or 6.1 mmol/L ≤ RPG < 12.2 mmol/L & HbA1c a 5.8% followed by FPG < 6.1 mmol/L (see Fig. 2).
c
NGT, Normal Glucose Tolerance; IFG, Impaired Fasting Glucose; IGT, Impaired Glucose Tolerance; N-T2D, Newly Diagnosed Type 2 Diabetes Mellitus; K-T2D, Previously Known Type 2 Diabetes Mellitus.
d
The prevalence is calculated from the entire group alive: age 74, n = 135; 75, n = 186; 76, n = 192; 77, n = 169.
