Question · asked by 1 review
Total daily fluoride intake (TDFI) and daily fluoride intake from toothpaste: Correlation between daily urinary fluoride excretion (DUFE) and fluoride intake
- Population
- Children and adults with 24-h urinary fluoride monitoring (9 studies reporting both intake and urine; Table 2)
- Intervention
- Total daily fluoride intake (TDFI) and daily fluoride intake from toothpaste
- Comparison
- Not specified
- Outcome
- Correlation between daily urinary fluoride excretion (DUFE) and fluoride intake
Daily urinary fluoride excretion was not correlated with total daily fluoride intake or with fluoride intake from toothpaste (R2 < 0.07), based on nine studies (ungraded).

How reviews are matched to this question
Reviews word the same question differently. Four decision models (TypeSafe's Jev, Liquid AI's d1-ultra, SubQ Snap and Baseten's Elephant) judged each wording of the population, intervention, comparator and outcome against the others; two wordings count as the same when at least three of them agree and none clearly disagrees, and findings count as this question only when all four elements match. Timing, setting and subgroup never split a question: they are shown on each finding.
