Figure 2.

Baseline (7:00am) biochemical differences between PA in the KCl group and those in the non-KCl group. KCl, patients with PA who received oral KCl (Span-K) supplementation; non-KCl, patients with PA who did not receive oral KCl supplementation; K⁺, potassium; Aldo, aldosterone; Timed U.Na⁺/Cr, 24-hour urinary sodium-to-creatinine ratio; Timed U.K⁺/Cr, 24-hour urinary potassium-to-creatinine ratio; Timed U.Na⁺/K⁺, 24-hour urinary sodium-to-potassium ratio. Spot U.Na⁺/Cr, spot urinary sodium-to-creatinine ratio; Spot U.K⁺/Cr, spot urinary potassium-to-creatinine ratio; Spot U.Na⁺/K⁺, spot urinary sodium-to-potassium ratio; P values on the basis of unpaired Wilcoxon test; median, the median value of each parameter in each group.
