The Associations Between Acid-Suppressive Drug Intake and Symptom Profiles in Functional Dyspepsia Patients Referred for Open-Access Endoscopy.
Observational study in United European gastroenterology journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFunctional dyspepsia (FD) is characterised by postprandial fullness, early satiation, epigastric pain, or burning without structural abnormalities on upper endoscopy. Proton pump inhibitors (PPIs) are the preferred first-line therapy. Given that the diagnosis of FD is largely based on symptom assessment, it remains unclear whether acid-suppression meaningfully influences symptom presentation.
objectiveThis exploratory study aimed to determine the prevalence of acid-suppressive therapy (PPIs or H2 receptor antagonists (H2RAs)) among FD patients and to compare symptom patterns between patients with and without these treatments.
methodsIn this single-centre, cross-sectional observational study, ambulatory patients referred for diagnostic upper endoscopy completed the Waiting Room Questionnaire (WRQ). Endoscopic findings were recorded, and FD was defined using Rome IV. Acid-suppression was defined as self-reported use of PPIs or H2RAs. Symptom frequency was compared between patients on and off therapy.
results1158 patients completed the WRQ; 27% fulfiled the criteria for FD. Among FD patients, 60% reported acid-suppressive therapy, similar to patients with endoscopic findings. FD patients receiving acid-suppression reported higher frequencies of early satiation (OR = 1.68, 95% CI 1.08-2.60), nausea (OR = 1.93, 95% CI 1.23-3.01), and epigastric pain (OR = 1.74, 95% CI 1.12-2.69). In subgroup analyses, therapy was associated with more frequent epigastric burning in postprandial distress syndrome (OR = 3.81, 95% CI 1.50-9.67) and higher frequencies of postprandial fullness (OR = 2.90, 95% CI 1.24-6.80) and early satiation (OR = 2.34, 95% CI 1.13-4.85) in the overlap subgroup.
conclusionsFD is prevalent in open-access endoscopy, and acid-suppressive therapy is frequently used in this population. FD patients receiving acid-suppression reported slightly higher frequencies of several symptoms, highlighting the need to further explore these associations.
