Figure 1. Pre- and postprandial blood glucose concentrations in relation to age.

(A) Preprandial nonfasting glucose concentrations (10 minutes before food intake) modeled using a general additive model with thin-plate splines. The model was developed using 5,952 measurements in 1,050 children. (B) Glucose concentrations in relation to age by linear regression before food intake (−10 minutes; red; n = 3,966 measurements from 1,050 children) and at 30 minutes (green; n = 3,608 measurements from 1,045 children) and 60 minutes (blue; n = 3,267 measurements from 1,042 children) after food intake.
