Mean (±1 SD) values for DXA measured whole body, total hip, and lumbar spine BMC, BA, BMD, BMC adjusted for bone area, height, and weight; lumbar spine BMAD; calcaneal BUA, BUA adjusted for height and weight, and BUA SD score. Mean values for vTBMD and vTBMD SD scores for children with CF are also shown
