Figure 1. Liver stiffness in participants ages 5–17 years.

The median liver shear wave velocity in m/s, a marker of liver stiffness, for each participant is plotted based on age. The top of each grey box represents the 97.5th %tile of the liver stiffness from a published cohort of healthy children of the same age using the GE Logiq E9 equipment used in this study[39]. The red line indicates the manufacturer’s cutoff for normal stiffness in adults.
