Box-and-whisker plot for HR-pQCT measured failure load in the radius (top) and tibia (bottom). Red lines, from top-to-bottom, represent 75^th, 50^th, and 25^th percentile in a reference population of young female adults aged 20-29 years-old [34]. Open points on total BMD (TtBMD) plot represent absolute values for osteopetrosis as there were not enough values to generate a box-and-whisker plot. Open square bracket with an asterisk (*) represents significance difference between two groups at an alpha value of 0.05
