Fig. 3. The predicted probability of having screen-detected diabetes with isolated elevated HbA1c or FPG.
a,b, The probability, by sex, age and region, of participants who did not have previous diagnosis of diabetes of having elevated HbA1c (≥6.5%) at different FPG and BMI levels (a) and elevated FPG (≥7.0 mmol l−1) at different HbA1c and BMI levels (b). The probabilities were calculated using coefficients of prediction equation model 8, with measurement method set to laboratory for prediction. These results show the probability of having screen-detected diabetes if the second biomarker had been measured, for a person whose first biomarker was below the clinical threshold for diabetes diagnosis.
