ALB and malnutrition: Figure 2D shows that the serum albumin values in this study were not significantly different (p > 0.05) among the treatment groups. Except for the casein group, which showed normal values (3.6 ± 0.15 g/dL), all diets produced serum albumin values in the range of 2.63–2.73 g/dL, which is classified as moderated malnutrition [39].
