Evaluation of radiation-induced bone marrow toxicity using artificial intelligence-based image analysis in mice.
Article in Toxicological research, 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
Radiation exposure profoundly affects bone marrow, with even low-dose exposure inducing notable biological changes. Traditional pathology methods often face challenges in detecting subtle alterations. However, artificial intelligence (AI) offers enhanced sensitivity and precision, enabling a more detailed analysis. This study aimed to evaluate the effect of whole-body irradiation (WBI) on blood parameters, bone marrow density, and apoptosis in mice, employing AI-based image analysis for accurate and efficient quantification of cell density and apoptosis. Female C57BL/6 mice (n = 120) were divided into four groups: a control group (Group 1) and three irradiated groups (Groups 2, 3, and 4), exposed to 0.5 Gy, 1 Gy, and 2 Gy of WBI, respectively. Mice were sacrificed at 1, 3, and 7 days post-irradiation for analysis. Blood samples were assessed for hematological changes, and the sternum was histopathologically evaluated. Despite stable body weights, WBI significantly altered blood parameters, reducing white blood cell and red blood cell counts while increasing platelet counts. Histopathological examination revealed a marked reduction in bone marrow cellularity in Groups 3 and 4 on day 1 post-irradiation; however, cellularity appeared to recover in these groups by days 3 and 7. AI-based image analysis of the sternum provided precise quantification, confirming a significant decrease in bone marrow cellularity in Groups 3 and 4 compared to Group 1 on day 1 (
