Box plot showing the mean vertical angle of osteons across the octants and circumferential rings. Blue represents the connected osteons between the superior and middle layers, a distance of approximately 300 μm. Green represents the connected osteons between the middle and inferior layers, a distance of approximately 300 μm. Purple encompasses the entire viewable osteon between the superior and inferior layers, a distance of approximately 810 μm.
