Radiation-induced Osteosarcoma in the Thoracic Cavity 28 Years after Irradiation for a Benign Disease: An Autopsy Case.
Article in Internal medicine (Tokyo, Japan), 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
A 60-year-old man with a history of radiation therapy 28 years ago for a benign disease (an aneurysmal bone cyst) was admitted with dyspnea and dysphagia. Computed tomography showed an 8-cm tumor invading the trachea and esophagus. His condition declined rapidly, and he died on day 27 of hospitalization. Autopsy revealed radiation-induced osteosarcoma. Radiation-induced sarcoma can develop even after radiotherapy for benign diseases, in which case the latency period might be longer. Furthermore, the prognosis depends on the location of the resectable tumor. Therefore, longer-term internal imaging follow-up should be performed after radiotherapy for benign diseases to detect early-stage sarcoma.
