Geant4-deoxyribonucleic Acid Simulation of Radiation-induced Deoxyribonucleic Acid Damage in a Human Cancer Cell Line.
Article in Journal of medical physics. 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
Introduction: Ionizing radiation causes deoxyribonucleic acid (DNA) damage through both direct and indirect mechanisms. This study aimed to investigate and quantify the biological response of ion beams in biological matter and the radiation-induced DNA damage using Monte Carlo (MC) simulations. The study provides insights into the potential benefits of novel helium ion beams in charged-particle cancer therapy. Materials and Methods: The Geant4-DNA MC toolkit was used to study the biological response to radiation and the resulting DNA damage. The MCF-7 breast adenocarcinoma cancer cell line was simulated. Helium ion beams with varying linear energy transfer values were irradiated onto the cancer cell line. Results: The radiobiological endpoints, in terms of damage yield and the single-strand break (SSB)/double-strand break (DSB) ratio, for the MCF-7 cancer cell line were retrieved and compared with published simulation-based studies and experimental studies. The damage yield and SSB/DSB ratio in this study were in good agreement with published simulation-based studies. However, the DSB yield in this study was higher than the experimental results from published studies. Conclusion: This study demonstrated the capabilities of the Geant4-DNA MC techniques in providing a mechanistic understanding of radiation-induced DNA damage in human cancer cell lines and quantifying the resulting DNA damage.
