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
introductionHepatocellular carcinoma (HCC) accounts for many cancer-related morbidity and mortality cases. This study aimed to assess the expression of circ-SMARCA5, circ-RHOT1, and hepatocyte nuclear factor 1 homeobox A (HNF1A). Analyze the protein expression of HNF1A, and identify HNF1A polymorphism and its correlation with HCC incidence and staging.
methodsIn this study, 48 HCC patients and 48 age-matched controls were selected. The expressions of circ-SMARCA5, circ-RHOT1, and HNF1A were determined using qRT-PCR in paired HCC and adjacent non-neoplastic liver tissues. HNF1A rs2464196 and rs1169310 polymorphisms were genotyped using TaqMan assays, while serum AFP concentrations were measured by ELISA.
resultsGA and AA genotypes of rs2464196 were more frequent among HCC cases and were associated with higher odds of HCC compared with the GG genotype, while CT and TT genotypes of rs1169310 were associated with higher risk compared to CC genotype. Also, A allele of rs2464196 and T allele of rs1169310 were more prevalent in patients with HCC. Circ-SMARCA5 and HNF1A expressions were significantly downregulated, whereas circ-RHOT1 expression was significantly upregulated in tumor tissues compared to adjacent non-neoplastic tissue (P < 0.001 for all). Circ-SMARCA5 and HNF1A expressions were correlated with lower serum AFP level, while circ-RHOT1 expression correlated with higher serum AFP. Lower circ-SMARCA5 and HNF1A expressions, and higher circ-RHOT1 expression were associated with advanced BCLC stage. Immunohistochemical staining showed reduced nuclear HNF1A expression in HCC tissues, which was associated with advanced BCLC stage and HNF1A variant genotypes.
conclusionThe association between HNF1A rs2464196 and rs1169310 genotypes and HCC susceptibility was found in the studied Egyptian population. Dysregulation of circ-SMARCA5, circ-RHOT1 and HNF1A expression, as well as reduced HNF1A protein expression were associated with HCC development and more advanced disease.
