The Cox regression analysis (shown in Table 4) showed that cardiovascular readmission within the first year after dialysis was associated with a higher risk of all-cause mortality (HR 2.66, 95% CI 1.91–3.70, p < 0.001) and CVD mortality (HR 3.42, 95%CI 2.20–5.31, p < 0.001) after adjusting for substantial confounders, including age, sex, DM history, CVD history, hypertension history, BMI, hemoglobin, albumin, calcium, phosphorus, TC, triglyceride, HDLC, LDLC, sodium, potassium, WCCr and RRF. This evidence concerns the gene ALB and hypertensive disorder.
