Figure 2.

Adjusted spline analysis for the association between serum uric acid (SUA) and all-cause mortality. Subdistribution hazard ratio and confidence intervals across different SUA levels are displayed. Black bars indicate the number of patients for different SUA levels (Q1, first quartile; M, median; Q3, third quartile). Adjustment was performed for age, sex, ethnicity, dialysis vintage, comorbidities (diabetes mellitus, cardiovascular disease, liver disease, and cancer), vascular access, lean tissue index (LTI), and fat tissue index (FTI).
