Where they differ
From the rowsThe best-graded row, grade B, is a meta-analysis of 1,826 people (2016) and found an improvement. 2 rows are graded No effect, our grade for adequately powered trials that found no effect.
The 3 rows that found an improvement were larger: a median of 857 people, against a median of 326 people for the 3 rows that found no difference.
Only the 3 rows that found an improvement include pooled reviews of several trials (1 of 3); the 3 rows that found no difference are single studies.
The best grade is B among the rows that found an improvement, and D among the rows that found no difference.

3 improved · 3 no difference- BGrade BAcute ear infections in healthy children at daycare (pooled) · Improved
Meta-analysis, 3 studies · n 1,826 · 2016 · Healthy Finnish children attending daycare in three randomized trials (five trials, 3,405 children, reviewed)
About 8 to 10 g/day in the pooled trials · 2 to 3 months
Acute otitis media fell from about 30% to 22% (RR 0.75, 95% CI 0.65 to 0.88; moderate-quality evidence). Xylitol did not help when given only during a respiratory infection (RR 1.13) or in otitis-prone children (RR 0.90). Abdominal discomfort and rash were no more common than with control.
- BGrade BAcute ear infections in daycare children: syrup, gum or lozenge · Improved
RCT · n 857 · 1998 · Healthy children recruited from day care centres, five randomized groups
8.4 g/day (gum) to 10 g/day (syrup) · 3 months
At least one ear infection occurred in 41% on control syrup vs 29% on xylitol syrup (a 30% decrease). Xylitol gum lowered the rate by 40% versus control gum; the 20% fall with lozenges was not significant. Children on xylitol syrup or gum needed antibiotics less often.
- BGrade BAcute ear infections in daycare children (chewing gum) · Improved
RCT · n 306 · 1996 · Children aged about 5 in eleven Oulu day care nurseries, most with past recurrent ear infections
8.4 g/day xylitol · 2 months
At least one ear infection occurred in 20.8% on sucrose gum vs 12.1% on xylitol gum (difference 8.7%, 95% CI 0.4% to 17.0%). Fewer children on xylitol received antibiotics (18.5% vs 28.9%). Two children on xylitol had diarrhoea.
- DGrade DEar infections in young children (xylitol syrup twice a day) · No difference
RCT · n 250 · 2024 · Children aged 1 to 5 years in 11 Canadian primary care practices (250 randomised)
Syrup twice a day (amount not stated in the abstract) · 6 months
Clinician-diagnosed ear infections: 6 with xylitol versus 3 with placebo (OR 2.04, 95% CI 0.43 to 12.92); no difference in colds or caregiver-reported cavities. Diarrhoea was the most common adverse event (34% xylitol, 28% placebo).
- ∅No effectAcute ear infections with xylitol three times a day · No difference
RCT · n 663 · 2007 · Healthy day care children during the respiratory infection season
9.6 g/day in three doses (control 0.5 g/day) · 3 months
At least one ear infection was diagnosed in 30% on control and 28% on xylitol; 142 vs 156 episodes in total. The differences were not significant.
- ∅No effectEar infections in otitis-prone young children (xylitol solution) · No difference
RCT · n 326 · 2014 · Otitis-prone children aged 6 months to 5 years in US primary care practices
5 g three times a day (15 g/day) · 3 months
Time to the first diagnosed ear infection did not differ (hazard ratio 0.88, 95% CI 0.61 to 1.3); episodes were 0.53 vs 0.59 per 90 days and antibiotic days 6.8 vs 6.4. Children who took nearly all their doses did no better.
