Relation of GDF15 with oral intake after ICU discharge. Plasma concentrations of GDF15 were quantified in 72 ICU patients on the last day in ICU and 7 days after ICU discharge. Macronutrient intake was scored semi-quantitatively based on estimated nutrient intake (low, moderate, and high intake meaning respectively < 40%, 40–60%, or > 60% of a normal intake). Geometric shapes represent means, and error bars represent standard errors of the mean. Numbers in the figure legend indicate the number of patients per group. Data are shown on a logarithmic scale
