Demographic and clinical data. Results were expressed in median [Q1-Q3] for quantitative data or number (percentage) for qualitative data. ‘n = ’ corresponds to the number of patients operated. HU—Hounsfield units. A p-value lower than 0.05 was considered as significant. p-value < 0.05 was highlighted in bold
