Vitamin D deficiency (serum 25(OH)D < 50 nmol/L) vs Normal vitamin D level (serum 25(OH)D ≥ 50 nmol/L): Dental caries

Population
Children (<19 years)
Intervention
Vitamin D deficiency (serum 25(OH)D < 50 nmol/L)
Comparison
Normal vitamin D level (serum 25(OH)D ≥ 50 nmol/L)
Outcome
Dental caries

Children with vitamin D deficiency had a 22% higher risk of dental caries than those with normal vitamin D levels (unadjusted RR 1.22; ungraded).

Studies behind the findings

The primary studies the full-text reviews tie to this outcome. Reviews with headline outcomes only do not list them here.

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.
