The Claim
Prophylactic zinc supplementation at 20 mg/day for two weeks in infants aged 6 to 14 months is not associated with a statistically significant reduction in the frequency of acute respiratory infection episodes, with an adjusted incidence rate ratio of 0.89 (95% CI 0.79–1.01).
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In infants aged 6 to 14 months, taking 20 mg of zinc daily for two weeks does not result in a statistically significant change in how often they get acute respiratory infections.
See the scientific wording
Prophylactic zinc supplementation at 20 mg/day for two weeks in infants aged 6 to 14 months is not associated with a statistically significant reduction in the frequency of acute respiratory infection episodes, with an adjusted incidence rate ratio of 0.89 (95% CI 0.79–1.01), indicating no clear preventive effect.
Giving zinc to babies raises zinc levels in their blood, which should help their immune cells work better and keep their airway lining strong, but this increase does not lead to fewer respiratory infections.
What the research says
1 studyGiving babies zinc supplements for a few weeks didn't make them get colds or pneumonia any less often, even though it might help them feel better faster if they do get sick.
