Multivariate Cox regression analysis revealed that Age (HR = 9.084;95%CI 5.912–13.959; p < 0.01), Diabetes (HR = 15.047; 95%CI 9.802–23.101; p < 0.01), Albumin (HR = 0.894; 95%CI 0.849–0.940; p < 0.01), Peritonitis (HR = 6.172; 95%CI 3.970–9.595; p < 0.01), Catheter-related complications (HR = 1.740; 95%CI 1.304–2.320; p < 0.01), and Mental state (HR = 2.261; 95%CI 1.589–3.217; p < 0.01) were identified as independent risk factors for PD technical survival in PD patients (Table 2). The gene discussed is ALB; the disease is peritonitis.
