Correlation of VEGF +405C/G Polymorphism with Gastrointestinal Tract Cancers Risk: An Updated Meta-Analysis.
Synthesis in Asian Pacific journal of cancer prevention : APJCP, 2025. 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
backgroundThe functional polymorphisms of VEGF can affect different cellular processes and play a major role in angiogenesis and tumor development. Several case-control studies have explored the association of VEGF +405C/G polymorphism with GIT cancer risk, however, the results were inconsistent. Therefore, the meta-analysis was conducted to clarify the association.
methodsBased on the inclusion and exclusion criteria, relevant data were extracted from PubMed, Google Scholar, Web of Science and Science Direct. Twenty three studies comprising 5,656 cases and 6,319 healthy controls were included in the present meta-analysis and the data was analysed by using online MetaGenyo software.
resultsIn the present study, no significant association was found in any of the genetic models in overall analysis as well as when data was stratified according to the ethnicity (p>0.05). After performing sub-group analysis on the basis of cancer type, significant association was found with increased risk of developing esophageal cancer under allele contrast, recessive, GG vs. CC and GG vs. GC models (p<0.05). Under overdominant model, VEGF +405C/G polymorphism was significantly associated with decreased risk of developing esophageal cancer (p=0.017) and GG vs. GC model showed a significant association with the risk of developing colorectal cancer (p=0.047) and pancreatic cancer (p=0.010). However, GC vs. CC model showed that VEGF +405C/G polymorphism was significantly associated with reduced risk of pancreatic cancer (p=0.039).
conclusionThe present updated meta-analysis suggested that VEGF +405C/G polymorphism may serve as a biomarker for determining an individual's risk of esophageal, colorectal and pancreatic cancer.
