Figure 2. Boxplots with dot plots of the volume percentages of brain parenchyma and lateral ventricles classified by age groups according to two different BMD groups. (A) Volume percentage of brain parenchyma to intracranial cavity classified by age groups according to osteoporosis; (B) volume percentage of lateral ventricles to intracranial cavity classified by age groups according to osteoporosis; (C) volume percentage of brain parenchyma to intracranial cavity classified by age groups based on normal, osteopenia, and osteoporosis groups; (D) volume percentage of lateral ventricles to intracranial cavity classified by age groups based on normal, osteopenia, and osteoporosis groups. BMD=bone mineral density; ICV=intracranial cavity volume; BPV=brain parenchymal volume; LVV=lateral ventricles volume.
