Univariable glioblastoma overall survival models using adipose tissue and skeletal muscle metrics.

*Asterisks denote significant univariable Cox-regression models using the group median value (50th) percentile as cutoff (Table 2, lower panel). All variables represent volumes of the respective metrics measured from the level of L1 through the L5 vertebrae. Abbreviations: AAC = abdominal aortic calcification; IMAT = intramuscular adipose tissue volume; SAT = subcutaneous adipose tissue volume; SKM fat fraction = ratio of IMAT over the SKM volume; SKM = total skeletal muscle (iliopsoas + abdominal wall muscles); TAT = total adipose tissue volume; VAT = visceral adipose tissue volume.
