BMI-stratified fracture distribution. Data in the histogram represent the ratio between fracture zone over the total of a weight class (\( \frac{\mathrm{N}\ \mathrm{patients}\ \mathrm{with}\ \mathrm{fracture}\ \mathrm{in}\ \mathrm{zone}\ \mathrm{n}}{\mathrm{Total}\ \mathrm{patients}\ \mathrm{in}\ \mathrm{considered}\ \mathrm{weight}\ \mathrm{class}} \)). Data in the table represent the ratio between weight class over the total of fractures zone \( \left(\frac{\mathrm{N}\ \mathrm{patients}\ \mathrm{in}\ \mathrm{considered}\ \mathrm{weight}\ \mathrm{class}}{\mathrm{Total}\ \mathrm{patients}\ \mathrm{with}\ \mathrm{fracture}\ \mathrm{in}\ \mathrm{zone}\ \mathrm{n}}\right) \). Note the growing distribution of proportion of zone 3 fractures with growing BMI (gray-coloured area)
