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
Host genetic factors influencing immune regulation are believed to modulate susceptibility to hepatitis C virus (HCV) and related hepatocellular carcinoma (HCC). This study aimed to investigate the association of Cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) genetic variants with HCV-related HCC risk, soluble CTLA-4 (sCTLA-4) levels, and disease severity. 225 age- and sex-matched participants (75 controls, 75 HCV, and 75 HCV-HCC) were enrolled. TaqMan allelic discrimination assays were used for genotyping three CTLA-4 SNPs, and sCTLA-4 was quantified by ELISA. Our results demonstrated that the rs231726 TT genotype and T-allele were significantly associated with HCC. The rs11571317 CC genotype and C-allele, alongside the rs13384548 GG genotype and G-allele, conferred increased risk for both HCV and HCC. Clinically, these high-risk genotypes correlated with worse liver function (Child-Pugh C), higher MELD/Na scores, and larger tumors. Moreover, sCTLA-4 levels showed a stepwise elevation from controls to HCV to HCC patients, peaking in carriers of the rs231726 TT and rs13384548 GG genotypes. In conclusion, this study identifies rs231726, rs11571317, and rs13384548 as robust genetic markers for HCV-related HCC susceptibility and cancer aggressiveness. Our findings provide novel evidence of their role in immune evasion through sCTLA-4 upregulation, offering new perspectives into genotype-based risk stratification and tailored immunotherapeutic strategies.
