Associations of overweight, obesity and osteoporosis with ankle fractures

Table 3 Odds of ankle fractures compared to controls, and of Danis- Weber types B and C compared to type A

Characteristics	Ankle fractures (n = 108) compared to controls (n = 199)		Danis-Weber B and C (n = 91) compared to Danis-Weber A (n = 17)

ORs are estimated using multivariable logistic regression models. Whiskers represent 95% confidence intervals
Reference category for osteoporosis was no osteoporosis (osteopenia and normal bone mineral density). Reference category for osteopenia was normal bone mineral density (T-score ≥ − 1.0)
