Figure 2. — Serum UA changed from baseline and its association with relative risk of RRF loss. The change of serum UA from baseline was regarded as a time-varying variable. A change of 0 (no change) compared to baseline was used as the reference (hazard ratio = 1.0) in both graphs. The areas between two dashed lines showed serum values with minimum risk of residual renal function (RRF) loss. Multivariate model (A) included the following variables: peritonitis, total KT/V urea. Multivariate model(B) included the following variables: age, gender, urate-lowering drug use, peritonitis, and total KT/V urea.
