Question · asked by 1 review
Genetically predicted gene expression (TWAS; S-PrediXcan with GTEx v8 cis-eQTL across 49 tissues; cross-tissue S-MultiXcan) vs ECC-unaffected children (association of genetically predicted expression): Early childhood caries (ECC) - association with genetically predicted expression of TAS2R14 (chr12p13.2)
- Population
- Children up to age 5-6 years (European / European non-Hispanic ancestry); 843 ECC-affected vs 2124 unaffected across 5 cohorts (N=2974)
- Intervention
- Genetically predicted gene expression (TWAS; S-PrediXcan with GTEx v8 cis-eQTL across 49 tissues; cross-tissue S-MultiXcan)
- Comparison
- ECC-unaffected children (association of genetically predicted expression)
- Outcome
- Early childhood caries (ECC) - association with genetically predicted expression of TAS2R14 (chr12p13.2)
Genetically predicted expression of TAS2R14 was significantly associated with ECC in the TWAS (p = 1.06e-6); genetic association, 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.
