We used the odds ratio (OR) for dichotomous outcomes presented with the corresponding 95% confidence interval (CI).
Pooled OR found a statistical difference favoring the PZN arm in the intention to treat and per protocol H. pylori eradication rates (OR: 2.01 with 95% CI [1.27, 3.21], p = 0.003) and (OR: 2.65 with 95% CI [1.55, 4.54], p = 0.0004), respectively.
We found no statistical difference between the two groups regarding the total adverse events (OR: 1.06 with 95% CI [0.55, 2.06], p = 0.85).

The dose-combined overall polaprezinc increased the change from baseline by a mean of 9.08 µg/dL (95% confidence interval: 5.46, 12.70; heterogeneity: I2 = 0.61%) compared to the placebo.
A significant dose-response relationship was confirmed (p < 0.001).
Baseline serum zinc concentration was considered an effect modifier in polaprezinc 300 mg.

Metaanalyses concluded that zinc sulfate failed to significantly reduce the incidence or severity of chemotherapy-induced oral mucositis, whereas polaprezinc was associated with a significant reduction.

For the primary efficacy endpoint, the effective rates confirmed by gastroscopy, after treatment for the test and control groups were 81.48% and 74.31% (P = 0.1557), respectively.
After 4 and 8 weeks of treatments, both treatment groups had comparable improvements rates in gastrointestinal symptoms (test vs. control: 44.44% vs. 39.45% [P = 0.4559] and 81.48% vs. 77.06% [P = 0.4223]).

Intention-to-treat (ITT) analysis showed that the rate of H. pylori eradication was significantly higher for Arms A (77.0%) and B (75.9%) compared to Arm C (58.6%) (P < 0.01), whereas there was no difference between Arms A and B (P = 0.90).
Per-protocol (PP) analysis showed that the rate of H. pylori eradication was significantly higher for Arms A (81.1%) and B (83.3%) compared to Arm C (61.4%) (P < 0.01), whereas there was no significant difference between Arms A and B (P = 0.62).
The adverse event rate for Arm B (5.1%) was higher than for Arms A (2.8%) (P = 0.04) and C (1.9%) (P = 0.02).

The geometric mean ratios (GMR) in primary PK endpoints between the test and reference products with 90% confidence intervals (CI) were calculated.

As a result, the zinc-treated arm experienced a statistically significant improvement against the placebo-treated arm in the perceptible threshold scores of the filter-paper disk method 8 weeks after the administration of the investigational drug.
However, the effective ratios based on the initial criteria were 55.6% in the treatment group and 43.2% in the placebo, where no statistical significance was recorded.
Whereas, in approximately 77%, or 168 patients with "normal" SDS scores and with completely impaired taste qualities, the ratio of effective cases reached 60.9% in the zinc-treated group, the ratio of the placebo-treated group reached 39.5%, resulting in a statistical significance.
The effect of a zinc-containing compound, Polaprezinc, was shown to clinically improve the disease conditions of idiopathic taste disorders with no serious side effects in a well controlled double-blinded clinical study.

The incidence of Grade ≥2 but not Grade ≥3 oral mucositis was significantly reduced in the prevention group compared to the control group (44.7% in control group vs 22.0% in the prevention group, P = .025).
There were no significant differences in the incidence rates of other adverse events or the rate of engraftment (95.6% vs 97.2%, P = .693) between the two groups.
A total of 91 patients were enrolled, and 88 patients (47 in the control group and 41 in the prevention group) were eligible for data analysis.
Zinc supplementation reduces ERI in patients undergoing HD and may be a novel therapeutic strategy for patients with renal anemia and low serum zinc levels.
Kobayashi H et al. · Nutrients (2015)
Serum zinc levels were significantly increased and serum copper levels were significantly decreased in the polaprezinc group after three months; this persisted throughout the study period.
Although there was no significant change in the serum iron or transferrin saturation levels in the polaprezinc group during the study period, serum ferritin levels significantly decreased following polaprezinc treatment.
Further, in the polaprezinc group, ESA dosage and ERI were significantly decreased at 10 months and nine months, respectively, as compared with the baseline value.
The polaprezinc plus PPI treatment showed noninferiority to rebamipide plus PPI treatment in the ulcer healing rate at 4 weeks after ESD.

The mean interleukin-6/maximal creatine phosphokinase level was significantly reduced in the polaprezinc group (0.024 [0.003-0.066] vs. 0.076 [0.015-0.212], respectively; P = .045).
In addition, echocardiography revealed that the ejection fraction of the nonpolaprezinc group was not significantly increased between day 3 and 9 months post-AMI (53 [49-60.8] vs. 59.5 [52-69.3], respectively; P = .015).
However, a significant increase was detected in the ejection fraction of the polaprezinc group at the 2 time points (54 [51-57] vs. 62 [55-71], respectively; P < .01).

Body temperature increased 2°C, and gut permeability (5-h urinary lactulose:rhamnose ratios) increased 3-fold after exercise (from 0.32 ± 0.016 baseline to 1.0 ± 0.017 at 14 d; P < 0.01).
ZnC or colostrum truncated the rise by 70% after 14 d of treatment.
The combination treatment gave an additional benefit, and truncated exercise induced increase at 2 d (30% reduction; P < 0.01).
