Table 2.
Quantitative body composition measurements by CT using of study patients. SKI = skeletal muscle cross sectional area (cm2)/(height (m))2. ADI = adipose tissue cross sectional area (cm2)/(height (m))2. Estimated skeletal muscle mass (kg) = 0.3 x [skeletal muscle at L3 (cm2)] + 6.06. Estimated fat mass (kg) = 0.042 x [total adipose tissue at L3 (cm2)] + 11.2.
