Compared with Q1, the fully adjusted hazard ratios (Model 3; adjusted for age, sex, NT-proBNP, dialysis duration, diabetes mellitus, cardiovascular disease, smoking status, serum creatinine, hemoglobin, GNRI, Kt/V, and CRP) were significantly lower in higher quartiles: Q2, HR 3.59 (95% CI 1.54–8.35, p = 0.002); Q3, HR 11.70 (95% CI 4.10–33.37, p < 0.001); and Q4, HR 3.96 (95% CI 1.74–8.99, p = 0.001) (Supplementary Table S3). The gene discussed is NPPB; the disease is diabetes mellitus.
