The relationship between plasma amino acids and circulating albumin and haemoglobin in postabsorptive stroke patients.
<h4>Background</h4>This retrospective study had two main aims: (1) to document possible correlations between plasma Amino Acids (AAs) and circulating Albumin (Alb) and Haemoglobin (Hb); and (2) to identify which AAs were predictors of Alb and Hb.<h4>Methods</h4>The study cons...
