Central versus peripheral BD, PD, and CTVF by laminar depth. Full-thickness (left) and inner, middle, and outer layer (right) data are shown. Overall, BD is significantly smaller within the peripheral subsectors of sectors 12, 1, 3, and 6. PD is significantly smaller within the peripheral subsectors of sectors 1, 3, 4, and 5. Connective tissue volume fraction is significantly smaller within the peripheral subsectors of sectors 11, 12, and 6. The overall relationships are most consistently present within the middle laminar layer data for each parameter.
