Linear regression of preprandial (10 minutes before food intake, A–D) and postprandial glucose values (30 minutes after intake, E–F) by visit age in the infancy period (visits 1–4; 4 months–1.35 years of age) and the toddler period (visits 5–9; 1.5–3.6 years of age). Analyses were separated by sex (A and E; boys [blue] vs. girls [red]), BMI (B; above the median [blue] vs. below the median [red]), glucose GRS (C and F; above the median [blue] vs. below the median [red]), and by INS genotype (D; AA [blue] vs. other [red]). Comparisons of regression coefficients between groups were performed using Student’s t test.
