The Claim
Intermittent zinc supplementation in infants is associated with a mean increase in weight gain of 332 grams and length gain of 1.4 cm over six months, with standardized mean differences in weight-for-age and length-for-age Z-scores of 0.32 and 0.14, respectively.
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.
Infants who receive intermittent zinc supplements gain an average of 332 grams more in weight and 1.4 centimeters more in length over six months compared to those who do not, with higher standardized growth scores for weight and length.
