Multiple LTF gene variants (joint / gene-based) vs Caries-free controls: Dental caries

Population
Individuals assessed for dental caries (cases with caries/high caries vs. caries-free or low/very-low-caries controls)
Intervention
Multiple LTF gene variants (joint / gene-based)
Comparison
Caries-free controls
Outcome
Dental caries

A gene-based analysis indicated that multiple LTF variants were jointly associated with dental caries risk (weighted TPM P = 0.0007; no pooled effect estimate; 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.
