Multivariate Cox regression analysis identified six independent predictors of PD technical survival: age ≥60 years (hazard ratio [HR] = 9.084, 95% confidence interval [CI]:5.912–13.959), history of diabetes mellitus (HR = 15.047, 95%CI:9.802–23.101), albumin level (HR = 0.894, 95%CI:0.849–0.940), peritonitis (HR = 6.172, 95%CI:3.970–9.595), catheter-related complications (HR = 1.740, 95%CI:1.304–2.320), and abnormal mental state (HR = 2.261, 95%CI:1.589–3.217) (all p < 0.01). The gene discussed is ALB; the disease is peritonitis.
