Fig. 2From: Bone mineral density in lower thoracic vertebra for osteoporosis diagnosis in older adults during CT lung cancer screeningThe difference between thoracic vertebral bone mineral density (TBMD) and lumbar bone mineral density (LBMD) (A) and the performance of thoracic vertebral bone mineral density (TBMD) in identifying osteopenia and osteoporosis based one ACR criteria (B) in population one. Kappa test showed moderate agreement in identifying osteoporosis between TBMD and lumbar spine BMD (kappa = 0.66) (B)Back to article page
