The overall proportions of subjects using any class of diuretic in each CKD stage.

<p>The differences between the proportions of subjects using any class of diuretic in each CKD stage were examined using chi-squared test (non-diuretic use vs. diuretic use) followed by a <i>post hoc</i> Bonferroni’s correction for comparisons between CKD stages. The proportions of subjects using any class of diuretic were higher in advanced CKD stages (stage 4, 5) (<i>P</i>-value <0.05).
