Analysis C showed that HD duration (OR: 1.203, 95% CI: 1.138–1.273, p < .001), nPCR (OR: 3.207, 95% CI: 1.273–8.078, p = .013), hypoalbuminemia (albumin <4 g/dL; OR: 2.221, 95% CI: 1.284–3.842, p = .004), and BLL >12.3 μg/dL (OR: 6.827, 95% CI: 3.737–12.472, p < .001) were positively associated with CTS (Table 6). The gene discussed is ALB; the disease is Hypoalbuminemia.
