Zinc Acetate Hydrate Supplementation versus Polaprezinc Supplementation for Improving Hypozincemia in Hemodialysis Patients: A Randomized Clinical Trial

Figure 2

Effects of zinc supplementation on trace elements. (a) The mean serum zinc levels are significantly increased from baseline to all the observation points in both the ZAH and PPZ groups. (b) The achievement rate of a zinc level ≥80 μg/dL is significantly higher in the ZAH group than in the PPZ group at 4–12 weeks. (c) The mean serum copper levels in the ZAH group decreased significantly from baseline to 16 weeks and 20 weeks, while those in the PPZ group did not significantly change during the observation period. (d) The mean alkaline phosphatase levels did not change in either group during the observation period.
