Susceptibility Polymorphism in the Promoter Region of IL-4 and IL-13 in Individuals with Periodontitis: A Systematic Review
Bibliographic record
Abstract
Objective: To understand the susceptibility to single nucleotide polymorphisms in the promoter region of Interleukin-4 (IL-4) and Interleukin-13 (IL-13) in patients with and without periodontal disease. Thus, a systematic review of available studies on the subject was performed. Material and Methods: A protocol was conducted for registration in the International Prospective Register of Systematic Reviews (PROSPERO) under CRD42021246646. For this search, studies were selected from the Scopus, Web of Science, Virtual Health Library, Embase, Cochrane Library, and PubMed databases. The selection criteria consisted of case-control and cohort studies published in English that had data on IL-4 and IL-13 genetic polymorphisms in patients with and without periodontal disease in the same study. The obtained studies were managed by EndNote Program™ X7 version and the Rayyan Platform. Regarding the risk of bias, we used the Newcastle-Ottawa Scale, which classified the studies using high-quality methodology. Results: After the selection process, three studies presented the eligibility criteria. No relation between IL-13 and susceptibility to periodontal disease was found. IL-4 gene (IL-4 -590C/T; IL-4-34C/T; rs2243248) was associated with susceptibility to the development of periodontitis. Conclusion: An association between IL-4 and the susceptibility of periodontitis was verified. Further case-control studies are needed to create more concrete conclusions on the subject.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
