Total number of patients and percentages are calculated based on 483 cases, which is the number of CT scans that could be used for adipose tissue analysis. Notice that these figures were slightly different in muscle and bone measurements due to technical limitations in these determinations (see main text for details). “Preadmission comorbidities” is a category that admits more than one item per patient; reason for admission is a category that only admits one item per patient.
