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
backgroundAlthough H. pylori is the most important risk factor for gastric cancer, the role of anti-H. pylori antibody titers in gastric carcinogenesis has not been investigated outside Asia. We aimed to analyze the relationship between H. pylori antibody titers and the risk of gastric precancerous lesions in a Caucasian population.
methodsWe analyzed the GISTAR pilot study data on participants from Latvia with available anti-H. pylori IgG antibody serology and histopathological information. Participants were classified into four groups according to antibody titer: low-negative (LN), high-negative (HN), low-positive (LP), and high-positive (HP). Odds ratios (ORs) for atrophic gastritis among the 4 groups were compared using logistic regression.
resultsAmong a total of 1725 individuals, 970 with available histopathological information were included. A total of 738 individuals (76.1%) had histologically diagnosed atrophic gastritis. Risk of histological atrophic gastritis for each group compared to LN was as follows: HN (OR, 1.52; 95% confidence interval (CI) 0.85-2.72), LP (OR 2.04; 95% CI 1.25-3.32), and HP (OR, 2.47; 95% CI 1.50-4.07). Antibody titer as a continuous variable showed a positive relationship with histological atrophic gastritis (OR 1.09 per 10 EIU; 95% CI 1.04-1.14). The positive relationship was clearer among those aged ≥ 50 years.
conclusionsAnti-H. pylori antibody titer was positively related to the risk of atrophic gastritis in a middle-aged Caucasian population, suggesting its potential complementary role in gastric cancer risk stratification in a European setting where upper endoscopic examination is less routinely available.
