Abbreviations: 1,5-AG, 1,5-anhydroglucitol; CI, confidence interval; IRR, incidence rate ratio.
a Model 1: no covariates (unadjusted).
b Among those with diagnosed diabetes, P < 0.05 for the estimate for the respective category of 1,5-anhydroglucitol (6.0–9.9 μg/mL or <6.0 μg/mL) relative to ≥10.0 μg/mL.
c Model 2 adjusted for demographics (age, sex, race).
d Model 3: model 2 with the addition of estimated glomerular filtration rate based on creatinine and cystatin C (modeled as linear spline terms with knots at 60 mL/min/1.73 m2 and 90 mL/min/1.73 m2).
e Model 4: model 3 with the addition of hypertension, body mass index, current smoking.
f Model 5a: model 4 with the addition of fasting glucose.
g Model 5b: model 4 with the addition of glycated hemoglobin.
