Based on the score scale, 166 patients were divided into a low-risk group (≤3 points) and a high-risk group (≥4 points), we calculated the perioperative albumin changing values of the two groups and deduced both groups’ recommended preoperative albumin values by combining the respective average decreased albumin value with the diagnostic threshold of hypoalbuminemia (35 g/L). This evidence concerns the gene ALB and Hypoalbuminemia.
