Meta-Analysis of Genetic Variants Associated With HBV Infection Susceptibility and Hepatocellular Carcinoma Risk.
Synthesis in Journal of viral hepatitis, 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
Hepatitis B virus (HBV) and hepatocellular carcinoma (HCC) are serious medical problems worldwide. Today, many researchers believe that genetic variations play a major role in how easily someone gets infected and how the disease progresses over time. Although many genetic association studies have suggested various susceptibility loci, lack of consistent results across studies has limited clinical utility. We performed a comprehensive meta-analysis primarily involving East Asian cohorts. We analysed eight SNPs related to HBV infection and 11 SNPs related to HCC across multiple etiologic subgroups. We found that CD40 rs1883832 and C2 rs9267665 exhibited the strongest associations with susceptibility to HBV infection, with no heterogeneity. We found that HLA-DPA1 rs3077 and HLA-DQB1 rs2856718 were significantly associated with HBV infection susceptibility, though with considerable heterogeneity. In our HCC analyses, we found that certain risk variants are linked to specific causes. These include HBV, HCV, alcohol-related disease, and non-alcoholic fatty liver disease (NAFLD). Each cause seems to have its own genetic factors. Based on these results, our meta-analysis brings together many studies to give a clearer picture of the genetic factors that influence HBV infection and HCC in different etiologic pathways. We found that immune-related genes and HLA class II variants seem to have roles in HBV persistence, while metabolic gene variants are major contributors to HCC risk.
