The biochemical analysis (Table 2) revealed lower serum albumin (ESRD: 4.3 ± 0.4; HD: 4.1 ± 0.4; PD: 3.8 ± 0.5), total proteins (HD: 6.7 ± 0.7; PD: 6.4 ± 1.4), and hemoglobin (ESRD: 11.7 ± 2.2; HD: 12 ± 1.6; PD: 11.7 ± 1.5) levels in chronic kidney disease (CKD) patients compared to HS and KT recipients (p < 0.001). This evidence concerns the gene ALB and chronic kidney disease.
