* Lower extremity sarcoma patients subgrouped into sarcomas within the vicinity of primary weight-bearing joints (femur/tibia) and pelvis/fibula.
CI = confidence interval, aBMD = areal bone mineral density (g/cm2), vBMD = volumetric bone mineral density (g/cm3), BMC = bone mineral content (g), UpEx = Upper Extremity, FN =femoral neck, Calc = calcaneus
