ESM Figure 1: Panel a: Distribution of times of best match of CGM data with the post-challenge OGTT glucose values. Panel b: Mean (95%-CI) plasma glucose levels measured during the OGTT (blue points) and simultaneously by the continuous glucose monitoring device (black curve) in 120 persons with prediabetes examined three times over 26 weeks. Analyses are based on baseline data only. The mean (SD) differences between observed CGM and OGTT glucose concentrations were 0.1 (0.7) mmol/L at time 0 min, -1.1 (1.3) mmol/L at 30 min, -1.5 (1.9) mmol/L at 60 min, and -0.6 (1.2) mmol/L at 120 min.
