Esomeprazole 40 mg Once a Day in Patients with Functional Dyspepsia: The Randomized, Placebo-Controlled “ENTER” Trial
Bibliographic record
Abstract
OBJECTIVE: The etiologies of functional dyspepsia (FD) are unclear, but in some studies, treatment with a proton pump inhibitor has been beneficial. The objective of this study was to evaluate the efficacy of esomeprazole 40 mg once a day compared to placebo in achieving symptom relief in primary care patients with FD. METHODS: This was a randomized, placebo-controlled trial in adult FD patients, who had at least moderate severity of symptoms, defined as a score of > or =4 on a 7-point Global Overall Symptom (GOS) scale. Patients were excluded if they had predominant symptoms of heartburn or regurgitation; after a normal baseline endoscopy, patients were randomized to esomeprazole 40 mg once daily or placebo for 8 wk. The primary outcome measure was symptom relief (GOS < or =2) at 8 wk. RESULTS: Of the 502 enrolled patients, 224 were randomized. The main reasons for exclusion were abnormal endoscopic findings, especially esophagitis. A significantly greater proportion of patients in the esomeprazole group achieved symptom relief at 4 but not at 8 wk compared to placebo: 4 wk esomeprazole 50.5% versus placebo 32.2%, p= 0.009; 8 wk esomeprazole 55.1% versus placebo 46.1%, p= 0.16. A similar relationship at 4 and 8 wk was seen for symptom resolution (GOS = 1) and improvement (DeltaGOS > or =2). CONCLUSION: For the primary outcome measure of symptom relief at 8 wk, there was no statistically significant difference between esomeprazole 40 mg once a day and placebo. However, at 4 wk, esomeprazole was significantly more effective than placebo for symptom relief. The difference in therapeutic gain between 4 and 8 wk was largely due to a higher placebo response rate at 8 wk.

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.
