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
BACKGROUND/
aimsPersistent dyspeptic symptoms are common during the proton pump inhibitor (PPI) washout period before Helicobacter pylori (H. pylori) testing. However, the role of rebamipide in symptom management during this interval remains unclear. MATERIALS AND
methodsThis double-blind, randomized controlled trial enrolled 65 patients with H. pylori-associated dyspepsia or gastritis, randomized (1:1) to receive rebamipide (100 mg 3 times daily) or placebo for 4 weeks, following a 14-day eradication regimen. The primary outcome was the proportion of responders achieving a ≥25% reduction in pain symptom scores on the Severity of Dyspepsia Assessment scale at week 6. Secondary outcomes included changes in pain symptoms, non-pain symptoms, and dyspepsia-related health scores, as well as eradication rates and safety.
resultsAll patients completed the trial. Although the proportion of responders was higher in the rebamipide group (18 patients, 56.3% vs. 13 patients, 39.4%), this difference was not statistically significant (P = .17). Scores for pain, non-pain, and dyspepsia-related health improved similarly in both groups. Eradication rates were comparable (87.5% vs. 90.0%), and no serious adverse events were reported.
conclusionThe responder rate was higher in the rebamipide group, but the difference did not reach statistical significance. The poten tial benefit of rebamipide as a rescue therapy during the PPI washout period before H. pylori testing warrants further investigation in larger trials.
