Helicobacter pylori infection is associated with elevated insulin resistance and cardiovascular risk, particularly in otherwise low-risk individuals: the Tongren health care study.
Article in BMC cardiovascular disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 AND
objectivesHelicobacter pylori (H. pylori) has been increasingly linked to extragastric conditions. However, the relationship between H. pylori infection and cardiovascular diseases (CVD) remains controversial. This study aims to investigate the association between H. pylori infection and 10-year cardiovascular risk.
methodsA total of 1,398 subjects who underwent health examinations at Beijing Tongren Hospital were included in this study. H. pylori infection was determined using
resultsIndividuals with H. pylori infection exhibited significantly higher TyG index and its derivatives (all P < 0.001), indicating increased insulin resistance. All TyG-related indices were strongly correlated with 10-year CVD risk, with TyG-WHR showing the strongest association (R = 0.745, P < 0.001). The estimated 10-year CVD risk was significantly higher in the H. pylori-infected group (P = 0.003). After adjusting for potential confounders, H. pylori infection remained independently associated with high cardiovascular risk (OR = 2.552, 95% CI: 1.312-4.963, P = 0.006). Notably, this association was more pronounced in females, individuals younger than 50 years, non-smokers, non-diabetics, and those without hypertension.
conclusionsH. pylori infection is associated with increased insulin resistance and elevated 10-year cardiovascular risk, particularly among individuals without traditional risk factors. These findings suggest that H. pylori infection may represent a non-traditional contributor to cardiovascular risk and warrants further investigation.
