Quantitative analysis of Epstein-Barr virus DNA in plasma and stomach biopsies of patients with gastric cancer.
Article in Virus genes, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Epstein-Barr virus (EBV) associated gastric carcinoma (EBVaGC) is a subtype of gastric cancer with distinct histological and molecular features. The study aimed to assess the EBV DNA copy number and the prevalence of EBVaGC in gastric cancer samples taken from Iranian patients. The next aim was to assess whether the DNA and microRNAs EBV are present in plasma. EBV load was analyzed in 68 gastric cancer biopsies and compared with the results of EBV-encoded small RNA in situ hybridization (EBER-ISH) test in these patients. After the detection of 6 EBV miRNAs in gastric tissue by stem-loop RT-PCR, plasma samples were evaluated for the viral load and EBV miRNAs. Four gastric cancer cases were EBER -ISH positive (5.8%), with a significantly higher viral load than the remaining cases, 47,781 vs. 1909 copies/μg of tissue DNA. Here, was also found a significant difference in plasma EBV load between EBER-positive and EBER-negative cases. Although EBV miRNAs were detectable in all the EBER-positive tumors, the test did not detect any of these miRNAs among the plasma samples tested. Our data indicate that the prevalence of EBVaGC among Iranian patients with gastric cancer is lower than the global prevalence and although none of the EBV miRNAs were detected in plasma, evaluation of EBV microRNAs in tumor tissue, especially miR-BART7-3p, may constitute useful biomarkers for diagnosis of EBVaGC.
