Fig. 1From: Advanced glycation end-products, measured as skin autofluorescence, associate with vascular stiffness in diabetic, pre-diabetic and normoglycemic individuals: a cross-sectional studyAssociations between skin AF and glycemic status in the EPIC-DZD study. N = 3535. Glycemic status was defined as follows: normoglycemic (HbA1c < 5.7% and no antidiabetic treatment), prediabetes (6.5% > HbA1c ≥ 5.7% and no antidiabetic treatment), diabetes (antidiabetic treatment, HbA1c ≥ 6.5% or prevalent diabetes at EPIC-Potsdam baseline). Differences in medians of skin AF were compared with 1-way ANOVA with Tukey–Kramer’s correction for multiple testing. Linear trend in skin AF across glycemic strata was assessed with linear regression. AF autofluorescence, HbA1c glycated hemoglobin 1CBack to article page
