After adjustment for age, sex, DM, history of CVD, 24-h urine output, hemoglobin, serum phosphorus, and serum albumin, peritonitis was independently associated with a higher risk of all-cause mortality (hazard ratio [HR] = 1.95, 95% CI: 1.46–2.60, p < 0.001), infection-related mortality (HR = 4.94, 95% CI: 2.47–9.86, p < 0.001), and CV mortality (HR = 1.90, 95% CI: 1.28–2.81, p < 0.001). The gene discussed is ALB; the disease is diabetes mellitus.
