Question · asked by 1 review
Higher drinking-water fluoride exposure vs Null / lowest drinking-water fluoride exposure (reference): Wrist fractures
- Population
- general population
- Intervention
- Higher drinking-water fluoride exposure
- Comparison
- Null / lowest drinking-water fluoride exposure (reference)
- Outcome
- Wrist fractures
Wrist-fracture risk declined nearly linearly with increasing fluoride: RR 1.00 at 0.01 mg/L to 0.84 at 1.5 mg/L drinking-water fluoride vs null; ungraded.

Higher drinking-water fluoride exposure vs Null / lowest drinking-water fluoride exposure (reference) Risk of wrist fractures · General population (both sexes, all ages) · Long-term / lifetime fluoride exposure, General population; 37 observational studies (1944-2024), predominantly North America (USA, Canada) and Northern Europe (Finland, Sweden), plus UK, Poland, Italy, Germany, China, Taiwan, South Korea, Ethiopia; exposure mainly community drinking-water fluoride, Drinking-water fluoride 1.5 mg/L vs null Wrist-fracture risk declined nearly linearly with increasing fluoride: RR 1.00 at 0.01 mg/L to 0.84 at 1.5 mg/L drinking-water fluoride vs null; ungraded. The association of fluoride exposure with bone density and fracture risk: a dose-response meta-analysis. (2025) All outcomes | RR 0.84 [0.43, 1.65] | Not reported | GRADE not reported |

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.
