Associations between clinical outcomes and body composition abnormalities related to: A) muscle mass; B) muscle composition; C) adipose tissue, in acute COVID-19 patients. Number of studies per variables is shown in parenthesis. Most variables were obtained from computed tomography images studies. Ten studies used bioelectrical impedance analysis and only 4 used ultrasound. Some studies evaluated >1 body composition compartment, and therefore, data presentation is reflected by that (that is, total number of studies reporting the relationship is higher than the absolute number of studies included in the review). ICU, intensive care unit; IMAT, intra- and intermuscular adipose tissue; SAT, subcutaneous adipose tissue; TAT, total adipose tissue; US, ultrasound; VAT, visceral adipose tissue; WC, waist circumference.
