Scatter and box plot of opercular measurement in comparison to age of subject The dots represent the scatter plot of operculum measurements (mm) by age of subject in years. The bar graphs represent the bottom offset axis for the median operculum measurements (mm) by the 4 age categories (0–3.9 years, 4–6.9 years, 7–9.9 years, and >10 years). To the eye, the boxes look like a trend toward increasing size with increasing patient age, but this is insignificant.
