These charts represent the "upper limit of normal" (mean +2 standard deviations) and are generated dynamically based on the tabular data published in the manuscript.
As noted in the manuscript: "Normal values differ by age, sex and race".
The #1 main finding of the study was "aortic dimensions were larger in males compared with females, and remained so when adjusted for height but not when adjusted for BSA."
