In patients with anaemia, no significant difference was observed in the postoperative Glu and Glu changes between the ANH group and the control group (p > 0.05); no significant difference was noted in the postoperative serum Alb and its decreasing value between the two groups (p > 0.05), as shown in Supplementary Table S2. The gene discussed is ALB; the disease is anemia (phenotype).
