HR (hazard ratio) indicates the relative increased risk of all-cause or cardiac death with each change in age, mean uric acid, uric acid variability, albumin, diabetes positive, or vascular access. reflected the interaction between uric acid and its variability. In multivariable regression analysis, these six variables were included in the same model.
