Association between Helicobacter pylori and Hepatobiliary Cancer: A Meta-analysis and Systematic Review.
Synthesis in Asian Pacific journal of cancer prevention : APJCP, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveHelicobacter pylori infections have been suggested to be associated with several extra gastric maladies, including hepatobiliary cancer (HBC). However, reports on the relationship between H. pylori infection and HBC showed variable and contrasting findings. This study aimed to address these contrasting findings and clarify the effect of H. pylori infections on HBC. Thus, we performed a systematic literature review of published related studies and a meta-analysis of eight eligible publications.
methodsRelated studies were searched in various database websites namely PubMed, ScienceDirect, Google Scholar, and Cochrane Library. Eligible studies were collated, and data were extracted. The odds ratio (OR) and 95% confidence interval (CI) were computed and interpreted using Review Manager 5.4.
resultsOur overall analysis showed a significant association between H. pylori infection and HBC risk. Post-outlier analysis revealed homogeneous data (I2 = 0%, p = 0.82) and significant association (OR: 2.63, 95% CI: 1.62-4.28, P < 0.0001). Subgroup analysis based on the method of diagnosis (PCR OR: 2.46, 95% CI: 1.37-4.42, P = 0.003; ELISA OR: 2.40, 95% CI = 0.99 - 5.85, P = 0.05) showed almost similar associations and odds ratios, but only the PCR group (I2 = 0%, P = 0.72) showed homogeneity. Subgroup analysis based on specimen types revealed consistent results for liver tissue (I2 = 0%, P = 0.82) and bile (I2= 0%, P = 0.76) samples, showing low heterogeneity. In contrast, serum samples (OR: 2.40, 95% CI = 0.99 - 5.85, P = 0.05) displayed a potential but statistically nonsignificant association, while bile samples demonstrated a significant association (OR: 3.65, 95% CI: 1.56-8.52, P = 0.003).
conclusionOverall, the present study suggests that H. pylori infection is associated with increased susceptibility to HBC development, with an increased effect found in bile and serum samples as specimens of choice for diagnosing H. pylori.
