The Impact of Helicobacter pylori Infection on Retinal Nerve Fiber Layer and Macula.

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
Purpose: This study aims to elucidate the effects of Helicobacter pylori infection on the retinal nerve fiber layer (RNFL) and macula. Methods: A cross-sectional study was undertaken at the Health Examination Center of the First Hospital of Handan from 2021 to 2022. Participants who underwent both the 14C-urea breath test and ocular examinations were selected. The RNFL and macula were assessed using a swept-source optical coherence tomography device (Topcon OCT, Tokyo, Japan). Data are presented as mean ± SD and were analyzed using the Mann-Whitney U-test and t-test, with a significance level set at P < 0.05. Results: RNFL analysis of 1693 H. pylori-positive and 1693 negative left eyes revealed significantly thinner inferior temporal RNFL in the H. pylori-positive group (149.79 ± 29.55 µm vs. 152.76 ± 29.15 µm, P = 0.026). No other regional RNFL differences were found (P > 0.05). In the macula study of 2117 H. pylori-positive and 2117 negative participants, macular degeneration occurred in 74 positive (avgerage age 54.66 ± 10.08 years) and 67 negative individuals (avgerage age 60.22 ± 10.50 years). The incidence rates were not significantly different (P > 0.05), but the positive group with lesions was significantly younger (P = 0.002). Conclusions: H. pylori infection may be associated with localized defects in the RNFL, which could serve as early indicators of glaucoma, and it may also be potentially linked to accelerated progression of macular degeneration.
