Appendix 1—table 19. General linear models: anthropometric predictors of thoracic vertebral BMD (mg/cm3) for women.
Height is included in models 1 and 3, weight in models 2, 3 and 5, body mass index (BMI) in model 4, body fat (% or fat mass) in models 5–6, and fat-free mass in model 6. Age is controlled in all models. Standardized betas are shown (intercepts omitted).
