3.2.2. Plasma Protein
At the baseline, the prealbumin levels < 2.91 μmol/L, as a sensitive indicator of low nutritional status, were found in 5%, 6%, and 6% in the WE, PS and C groups, respectively. The plasma concentrations of both prealbumins increased significantly by 0.24 μmol/L (95% CI, 0.12 to 0.35) in WE compared to the PS and C groups at week 14 and 35 (
