Does Epstein-Barr virus-positive gastric cancer establish a significant relationship with the multiple genes related to gastric carcinogenesis?
Article in PloS one, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
Gastric cancer has been categorized into molecular subtypes including Epstein-Barr virus (EBV)-positive tumors, which provide clinicopathological and prognostic information. In this study, we investigated the EBV infection status of patients with gastric cancer and its correlation with the clinicopathological characteristics and multiple genes related to gastric carcinogenesis. The data of 460 gastric cancer patients who underwent curative gastrectomy with D2 lymph node dissection between January 2017 and February 2022 were analyzed. The clinicopathological features and prognosis of the patients with EBV-positive gastric cancers were compared with those of EBV-negative gastric cancers. Immunohistochemistry for epidermal growth factor receptor (EGFR), C-erb B2, Ki-67, and p53 was performed. Additionally, in situ hybridization was conducted to detect EBV, and microsatellite instability (MSI) analysis was used to assess the deficiency in mismatch repair (MMR) genes. EBV-positivity and MSI were identified in 10.4% and 37.3% of gastric cancer patients, respectively. EBV positivity was associated with male gender (P = 0.001), proximal location (P = 0.004), poorly differentiated histological type (P = 0.048), moderate to severe lymphoid stroma (P = 0.006), high Ki-67 expression (P = 0.02), and a shorter resection margin. EGFR was more often expressed in EBV-negative gastric cancers (P < 0.001). MSI tumors were associated with older age (P = 0.01), the presence of lymphatic invasion (P = 0.02), less perineural invasion (P = 0.05), and the presence of H. pylori infection (P = 0.05). EBV positive gastric cancer is associated with increased Ki-67 and decreased EGFR expression and a shorter resection margin due to the prominent lymphoid stroma. However, MMR deficiency is not associated with EBV status even though MSI gastric cancer is related to H. pylori status.
