Abstract
It has been 2 decades since the rediscovery of Helicobacter pylori. Since that time, enormous advances have occurred: H. pylori is clearly felt to be a cause of peptic ulcer disease and gastric malignancies such as mucosa associated lymphoid tissue (MALT) lymphoma and a carcinogenic factor for gastric adenocarcinoma. These associations have led to clear indications for H. pylori treatment in certain conditions, but in other diseases where the associations are not as clear, the indications also remain relatively controversial. Clear indications for H. pylori treatment include patients with duodenal and gastric H. pylori associated ulcers and MALT lymphoma. In uninvestigated dyspepsia, there are also very clear benefits to H. pylori treatment whereas in non-ulcer dyspepsia, the benefits are controversial. H. pylori is certainly a risk factor for gastric adenocarcinoma but eradication of this infection has not yet been shown to reduce or eliminate the risk of developing this condition. The effect of H. pylori treatment in patients with gastroesophageal reflux disease is also unclear. There is a potential benefit in the prevention of atrophic gastritis but a potential disadvantage is the worsening of reflux disease, which has been suggested by certain studies. In addition, the interaction between H. pylori and nonsteroidal anti-inflammatory drugs (NSAIDs) appears quite complicated. Although there have been several advances in the last 2 decades with regards to the treatment of H. pylori, several controversies still exist, attesting to the requirement for further research.

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.
