In particular, high RDW value remains associated with vertebral fractures even after adjusting for all considered possible confounders: age, BMI, menopause, nutritional status (total protein, albumin, calcium phosphate), smoking, osteoporosis and anemia (OR = 4.1, 95% CI 1.67–11.4, p = 0.003), (Table 4). Here, ALB is linked to osteoporosis.
