Figure 1

Simple renal cysts (SRC) prevalence in groups with different serum uric acid levels. The subjects were divided into seven groups by 60-µmol/L increments in serum uric acid (no further stratification for subjects with serum uric acid level ≤240 µmol/L or >540 µmol/L). The P-value was <0.05 when the a and b groups were compared.
