Changes in median extracellular mass/body cell mass in malnourished (body mass index < 18.5) vs normal/overweight patients (body mass index ≥ 18.5) over time (time points T1–T5).

	BMI < 18.5	BMI ≥ 18.5	ΔECM/BCM	p-value
ECM/BCM ratio; median (range)
T1	1.43 (0.47–3.80), n = 16	1.05 (0.68–2.25), n = 42	26.6%	0.003
T2	1.31 (1.10–5.13), n = 12	0.97 (0.68–1.39), n = 26	26.0%	<0.001
T3	1.25 (1.05–5.81), n = 7	0.97 (0.53–1.50), n = 22	22.4%	0.003
T4	1.35 (1.04–2.49), n = 3	1.04 (0.75–1.23), n = 11	22.4%	n.d.
T5	1.34 (1.12–2.90), n = 3	1.06 (0.71–1.25), n = 5	20.9%	n.d.

The median observation period per patient was 10.3 months (interquartile range: 0.3; 18.4). Normal range of extracellular mass/body cell mass: < 1.0.

BMI: body mass index; ECM: extracellular mass; BCM: body cell mass; n.d.: not done due to low patient numbers per group.
