BMI—body mass index; AC—arm circumference; TSF—triceps skinfold; FM—fat mass; FFM—fat-free mass; BIA—bioelectrical impedance analysis; R/H—resistance over height: Xc/H—reactance over height; PA—phase angle; kcals/d—kilocalories/day; kcals/AW/d—kilocalories/kilograms of actual weight/day; g/d—grams/day; g/kgAW/d—grams/kilograms of actual weight/day;; nPNA—normalized protein nitrogen appearance. Continuous variables are expressed as mean ± SD or median with interquartile range in case of non-normally distributed data, and categorical variables are expressed as a percentage. p < 0.05 was considered statistically significant.
