Prevalence, infection status and associated factors of H. Pylori among adult dyspeptic patients in Jalalabad, Afghanistan.
Article in BMC infectious diseases, 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
backgroundHelicobacter pylori is a globally prevalent chronic bacterial infection, disproportionately affecting low- and middle-income countries. Despite its significant gastrointestinal burden, epidemiological data from Afghanistan are limited. This study aimed to determine the prevalence, infection status, and associated factors of H. Pylori among adult dyspeptic patients in Jalalabad.
methodsA cross-sectional study was conducted in Jalalabad, Afghanistan, from August 2023 to February 2024 among 363 adult dyspeptic patients. Cumulative H. pylori prevalence was defined by serum IgG and/or stool antigen positivity, active infection by stool antigen alone, and associated factors were identified using multivariable logistic regression (p < 0.05) analysis.
resultsThe cumulative prevalence of Helicobacter pylori infection was 79.1% (287/363), defined by combined serum IgG and/or stool antigen positivity. Infection status included chronic active infection (41.3%), acute infection (20.7%), prior exposure (17.1%), and non-infected status (20.9%). Independent factors associated with cumulative H. pylori infection were age ≥ 50 years (AOR = 6.50), married status (AOR = 3.90), low education (AOR = 2.20-5.80), multigenerational households (AOR = 7.30-7.50), crowded sleeping conditions (AOR = 2.30-4.50), family history of gastric disease (AOR = 8.90), low income (AOR = 4.80-9.20), and shared drinking glass use (AOR = 12.30). All associations were statistically significant (p ≤ 0.03).
conclusionH. pylori affects 79.1% of dyspeptic adults in Jalalabad, with higher risk among older, married, low-education/income individuals, multigenerational households, crowded sleeping, shared drinking, or family history, highlighting the need for targeted interventions in this high-prevalence, resource-limited setting. CLINICAL TRIAL: Not applicable.
