- In this randomized controlled trial, zinc lozenges with 10 mg zinc
each were used. Children in grades 1 - 6 took the lozenges 5 times/day,
grades 7 - 12 took the lozenges 6 times/day. Placebo lozenges
were as close as possible in texture and taste.
- End points were measured as days until resolution of all symptoms,
days until resolution of individual symptoms, and school absences.
- Median number of days until resolution of all symptoms: Zinc group
= 9 days, Placebo group = 9 days, p = .71.
- School absences - Total number of days missed: Zinc group = 32, Placebo
group = 53, P = .12.
