Abbreviations: GFR glomerular filtration rate, FFMI fat free mass index, FMI fat mass index, DXA dual energy-x-ray absorptiometry, BIS bio-impedance spectroscopy, UNA urinary urea nitrogen appearance
Calculations: FMI = body fat (kg) / squared height in meters; FFMI = Body weight (kg) – body fat (kg)/squared height in meters
Reference values for FFMI and FMI according to the Swedish National Board of Health and Welfare’s cut-off values for malnutrition [23]: FFMI: Women <15 kg/m², Men <17 kg/m²; FMI: Women <4 kg/m², Men <2 kg/m²
