Table 1.
Subject characteristics by glucose and fasting status.
Figure 1.
Overall associations of S-Fructosamine with S-Glucose and B-HbA1c respectively.
All fasting states and all levels of glycemia included (All subjects).
Figure 2.
Correlations of S-Fructosamine and B-HbA1c by fasting status, type 2 diabetes (new and diagnosed) and type 1 diabetes.
Fitted regression line with 95% confidence and prediction limits. Reference lines at fructosamine 2.5 mmol/L and at HbA1c 6.5% (48 mmol/mol).
Figure 3.
Mean values of S-Fructosamine, S-Glucose and B-HbA1c over time by increase/reduction of S-Glucose at on average 290 days after the index examination.
Fasting subjects with new or diagnosed type 2 diabetes and with three simultaneous measurements of the biomarkers within one year are included.
Figure 4.
Individual changes and correlations of S-Fructosamine, S-Glucose and B-HbA1c over time.
Fasting subjects with new or diagnosed type 2 diabetes and with three simultaneous measurements of the biomarkers within one year are included.
Figure 5.
Mean values of fasting serum glucose and HbA1c by percentiles of S-Fructosamine with corresponding 1 standard deviation.
Sensitivity/Specificity at various fructosamine cut-off values for diagnosis of diabetes according to ADA criteria, 2.3 mmol/L (79%, 88%), 2.5 mmol/L (61%, 97%), 2.6 mmol/L (52%, 99%). Diagnostic discrimination of diabetes by S-Fructosamine using ROC analysis: AUC = 0.91 (fasting) AUC = 0.95 (non-fasting).
