Furthermore, when hypoalbuminemia was categorized into mild and severe levels, the results also showed that lower albumin levels correlated with a higher risk of CIA (OR, 3.65; 95% CI, 2.77–4.76 for mild vs. OR, 5.10; 95% CI, 2.22–10.22 for severe) (Figure 3; Supplementary Table S3). This evidence concerns the gene ALB and Hypoalbuminemia.
