Helicobacter pylori infection among the Dayak community in Kuching Division, Sarawak: findings from a community-based study.
Article in BMC gastroenterology, 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
purposeHelicobacter pylori is a primary driver of peptic ulcer disease and gastric adenocarcinoma, yet epidemiological data regarding its prevalence among indigenous communities in Sarawak are scarce. This study aimed to determine the H. pylori seroprevalence and identify associated socio-demographic and lifestyle factors within the Dayak population.
methodIt was a cross-sectional study carried out in rural areas of Kuching Division. Data was collected using blood sampling, interview-guided questionnaires, and anthropometric measurements. The questionnaire included socio-demographic profiles, history of illness, smoking habit, alcohol consumption, physical activity, and dietary intake. Factor analysis was used to identify dietary patterns. Health profile including helicobacter pylori infection status, blood pressure and body mass index were collected.
resultA total of 199 respondents aged 18 to 91 years from six villages participated in this study, yielding a response rate of 96.6%. About 60% of the respondents were found to be overweight or obese, and 48.7% had hypertension. Blood test analysis detected H. pylori antibodies in 46.2% of the respondents. In the multivariate analysis, several factors were found to be significantly associated with the presence of H. pylori antibodies: increasing age (OR: 1.042, 95% CI: 1.011-1.074), lower systolic blood pressure (OR: 0.967, 95% CI: 0.941-0.994), high physical activity level (OR: 0.278, 95% CI: 0.121-0.640), and medium intake of nutritious food and dairy (OR: 3.364, 95% CI: 1.394-8.117).
conclusionImplementing community-level screening programs is essential for early detection and targeted intervention, which could ultimately reduce the burden of infection and its associated complications.
