Table 4 Comparison of characteristics of cancer patients with low muscle mass and normal muscle mass

From: Immunohistochemical phenotyping of T cells, granulocytes, and phagocytes in the muscle of cancer patients: association with radiologically defined muscle mass and gene expression

  1. Normal muscle mass: patients with SMI (cm2/m2) within the mean ± standard deviation (SD) of 30-year-old healthy individuals (males: 60.9 ± 7.8 cm2/m2//females: 47.5 + 6.6 cm2/m2) as reported by Derstine et al. [20] Differences between groups were analyzed by Mann-Whitney U test (non-categorical variables) and Fisher’s exact test (categorical variables) where appropriate. Statistical significance p < 0.05
