The association between low bone mass and vertebral compression fracture. Cumulative hazards of vertebral compression fracture stratified by osteopenia and osteoporosis based on threshold method (A) and translated thoracic vertebral bone mineral density (B), and one case of fracture in subjects with thoracic vertebral bone mineral density (TBMD) of 89 mg/cm³ at baseline (C). A: normal: TBMD > 128 mg/cm³; osteopenia: TBMD 91–128 mg/cm³; osteoporosis: TBMD < 91 mg/cm³. B: normal: TTBMD > 120 mg/cm³; osteopenia: TBMD 80–120 mg/cm³; osteoporosis: TBMD < 80 mg/cm³. C: A 77 year-old man with a TBMD of 89 mg/cm³ at 2016. Two years later, vertebral compression fractures occurred at T11 (Arrow)
