Serum K⁺levels. Serum K⁺ levels at baseline, 4 h post-infusion and 24 h post-infusion (mmol/l; 50 g amino acid vs. 75 g amino acid). **4 h in comparison to baseline (50 g/75 g): p?<?0.001; ^#4 h in comparison to 24 h (50 g/75 g): p?<?0.001; *24 h in comparison to baseline (50 g): p?<?0.05. Empty bars show serum K⁺ concentrations after administration of 50 g AA, and full bars show serum K⁺ concentrations after administration of 75 g AA.
