1 · What the graph read from it

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.

2 · The registry

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 AND

aimThe relationship between gastroesophageal reflux disease (GERD) and Helicobacter pylori is controversial. We evaluated endoscopic, 24-h gastric and esophageal acid profile among patients with GERD in relation to H. pylori, as the latter might alter gastric acid secretion.

methodsPatients with GERD (n = 123), who were not on acid-suppressive drugs, and had not received anti-H. pylori therapy, underwent gastroduodenoscopy and tests for H. pylori detection. Esophageal manometry, 24-h pH metry, serum pepsinogen-I (PG-I), PG-II and gastrin-17 ELISA were done in all these patients. Univariate and multivariate analyses were performed to assess independent predictors for erosive esophagitis (EE).

resultsOf 123 patients (mean age 40.5 [13.1] years, 85 [69.1%] men), 59 (47.9%) had H. pylori infection. EE was more common in H. pylori non-infected than infected (49 vs. 32, p < 0.001). Among patients older than 40 years, absence of H. pylori was associated with lower esophageal pH and longer reflux (p = 0.02 and p < 0.001, respectively). PG-I/PG-II ratio was lower in H. pylori infected subjects (p < 0.001). In patients with higher LA grade of esophagitis, elevated PG-I levels and PG-I/PG-II ratio were associated with more acidic stomach (p = 0.04 and p = 0.01, respectively). Multivariate analyses showed low gastrin-17 (p = 0.016), higher age (p = 0.013), hiatus hernia (p = 0.004) and absence of H. pylori (p = 0.03) were independent predictors for risk of EE.

conclusionH. pylori infection is associated with less acidic stomach and less severe GERD. Low gastrin-17, higher age, hiatus hernia and absence of H. pylori were the best predictors for EE risk.
