Additional file 3: of Bayesian hierarchical piecewise regression models: a tool to detect trajectory divergence between groups in long-term observational studies

Spaghetti plot of the individual trajectories of those with T2DM in adulthood (N = 88) and those who did not develop T2DM in adulthood (N = 2452). Red solid line: loess smoother curve indicating the average longitudinal trend in each group (Figure S1.) and scatterplot of the life-course BMI data (in kg/m2) stratified by sex. Solid lines and gray bands: loess smoothed average trajectories and confidence intervals for each group (adult T2DM vs. non-T2DM group); dashed lines: age-specific averages of BMI levels (Figure S2.)
