Association of LEPR Gln223Arg Polymorphism with Obstructive Sleep Apnea Syndrome: A Meta-Analysis
Bibliographic record
Abstract
Previous studies examining the association of leptin receptor (LEPR) Gln223Arg polymorphism with obstructive sleep apnea-hypopnea syndrome (OSAHS) risk have yielded controversial outcomes. We aimed to clarify whether LEPR Gln223Arg polymorphism was critically involved in the development of OSAHS. We thoroughly searched PubMed as well as CNKI datasets for collection of relevant studies, followed by analysis of odds ratios (ORs) with corresponding 95% confidence intervals (CIs). Of the seven case-control studies we enrolled, there was insignificant correlation of the LEPR Gln223Arg polymorphism with OSAHS risk. However, subgroup analysis by Newcastle-Ottawa scale (NOS) scores revealed that, LEPR Gln223Arg polymorphism was significantly related to OSAHS risk in high-quality studies. In addition, we found no publication bias. Our findings suggest that LEPR Gln223Arg polymorphism might contribute to the risk of OSAHS. Well-designed studies with more subjects are needed for further validation of these results.

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.
