Abstract
BACKGROUND: Dyspepsia is a global problem and the management of the condition remains a considerable burden on health care resources. Many countries have adopted evidence-based guidelines for the management of the condition, in an attempt to reduce health care expenditure. This article compares and contrasts dyspepsia management guidelines from several geographical regions. METHODS: We obtained current guidelines from five regions and examined composition of guideline development groups, methodology involved, definition of dyspepsia utilized, and recommendations in terms of first-line approach, age cutoff for prompt upper gastrointestinal (GI) endoscopy, and subsequent role of endoscopy. RESULTS: All guidelines carried out extensive reviews of the literature to inform their recommendations. The majority used a definition of dyspepsia in line with the Rome criteria. All agreed that alarm symptoms at any age warranted prompt endoscopy, and most recommended an age cutoff of between 50 and 55 years for endoscopy as an initial management strategy. In young patients without alarm symptoms, either 'test and treat' or empirical acid suppression were the initial management strategies of choice in all cases, with only one guideline recommending mandatory endoscopy in those whose symptoms failed to settle after this approach. CONCLUSIONS: Despite varying composition of guideline development groups and the different geographical regions, the recommendation of all the guidelines were remarkably similar, reflecting the quality of research conducted by the GI community as a whole.

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.
