Appendectomy and Risk of Parkinson’s Disease: A Systematic Review and Meta-analysis
Bibliographic record
Abstract
Embase through September 10, 2024 to identify potential literature. Main outcome(s) Risk of Parkinson's Disease. Quality assessment / Risk of bias analysisThe quality of the collected literature will be assessed using the Newcastle-Ottawa Scale (NOS).Studies with a score >=7 were considered high quality studies.Two researchers will independently conduct the quality assessments.Disagreements will be deferred to a third reviewer for the final decision after discussion. Strategy of data synthesisStatistic analyses of this study will be conducted using Review Manageer 5.4.A random-effects model will be employed.Statistical significance is defined as a p-value 50.Subgroup analysis Subgroup analyses will be conducted, including different subgroups such as sex.Sensitivity analysis Sensitivity analyses will be performed.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
