Fig. 4From: Bone mineral density in lower thoracic vertebra for osteoporosis diagnosis in older adults during CT lung cancer screeningA formula (LBMD = 0.9 × TBMD– 1.83) was obtained to translate lumbar bone mineral density (LBMD) based on thoracic BMD (TBMD) (A) and the performance of translated LBMD in identifying osteopenia and osteoporosis. Kappa test showed good agreement in identifying osteoporosis between translated LBMD (TTBMD) and LBMD (kappa = 0.82) (B)Back to article page
