Stacked bar chart representing the composition of the sample of respondents involved in this study. The majority of the sample were trauma and orthopedic surgeons, the rest of the sample is relatively varied, as also shown by the ‘other’ category, which is the second one for numerosity and encompasses (among the others) two neurologists, one endocrinologist and one rheumatologist. This suggests that, despite the relatively small sample, this is sufficiently heterogeneous not to consider the responses limited to a specific medical discipline
