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

backgroundHelicobacter pylori infection is reportedly associated with iron-deficiency anemia. However, little is known about the association between the endoscopic features of H. pylori in the Kyoto classification of gastritis and iron deficiency. Therefore, we analyzed the endoscopic features of H. pylori gastritis and studied the association between these endoscopic features and iron deficiency.

methodsWe retrospectively analyzed patients diagnosed with H. pylori gastritis between May 2022 and June 2023 who also underwent laboratory tests, including anemia profiling. Iron deficiency was defined as a ferritin level below 55 ng/mL. Multivariate analysis was used to assess the association between endoscopic features and iron deficiency.

resultsOf the included patients, 47 had iron deficiency. Female patients were significantly more common in the iron-deficient group (87.2% vs. 33.4%, p<0.001). Endoscopically, nodularity (46.8% vs. 23.4%, p=0.001) and hyperplastic polyps (17.0% vs. 3.7%, p=0.001) were more common in patients with iron deficiency. Multivariate analysis identified younger age, female sex, and larger hyperplastic polyps (≥5 mm) as independent risk factors for iron deficiency.

conclusionsYounger age, female sex, and larger hyperplastic polyps (≥5 mm) are associated with iron deficiency in patients with H. pylori gastritis. These features may help identify patients at higher risk of iron deficiency.
