Fig. 2. Effects of calcium polystyrene sulfonate on serum potassium. (A) Serum potassium concentrations were compared before and after administration of calcium polystyrene sulfonate (*, p<0.001 by paired t-test). (B) Serum potassium concentrations were lowered by calcium polystyrene sulfonate in a dose-dependent fashion (p<0.001 by oneway ANOVA test). https://doi.org/10.1371/journal.pone.0173542.g003.
