Causal relationship between Helicobacter pylori antibodies and gastroesophageal reflux disease (GERD): A mendelian study.
Article in PloS one, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundObservational studies have indicated that both Helicobacter pylori infection and the presence of Helicobacter pylori antibodies may increase the risk of gastroesophageal reflux disease (GERD). However, the exact association between Helicobacter pylori antibodies and the occurrence of GERD remains largely unresolved. Therefore, this two-sample Mendelian randomization (MR) study aims to investigate the causal relationship between Helicobacter pylori infection and GERD.
methodsThis study encompassed seven different specific protein antibodies targeting Helicobacter pylori and utilized a genome-wide association study (GWAS) on GERD. MR analysis was conducted to assess the causal relationship between Helicobacter pylori antibodies and the development of GERD.
resultsGenetically predicted serum levels of Helicobacter pylori IgG antibodies were positively associated with an increased risk of GERD (odds ratio [OR] = 1.001, 95% CI 1.000-1.003, P = 0.043). No causal relationship was found between other Helicobacter pylori antibodies and gastroesophageal reflux disease.
conclusionThe outcomes derived from our two-sample Mendelian randomization analysis demonstrate a discernible link between the levels of Helicobacter pylori IgG antibodies and an augmented susceptibility to GERD. However, it is imperative to expand the sample size further in order to corroborate the correlation between Helicobacter pylori infection and GERD.
