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: Complete resection is essential for the treatment of teratoma with malignant transformation, and if metastasis occurs, it will be difficult to cure. We report a case of primary mediastinal teratoma with differentiation into angiosarcoma that caused bone metastases but was cured by multidisciplinary treatment. Case presentation: A 31-year-old man with a primary mediastinal germ cell tumor underwent primary chemotherapy followed by post-chemotherapy resection, with angiosarcoma due to malignant transformation found in the surgical specimen. Femoral diaphyseal metastasis was manifested, and he underwent femur curettage followed by radiation therapy of 60 Gy in parallel with 4 cycles of chemotherapy combining gemcitabine and docetaxel. Although thoracic vertebral bone metastasis emerged 5 months after treatment, intensity-modulated radiation therapy was successful, and metastatic lesions have remained shrunken for 39 months after treatment. Conclusion: Even if complete resection is difficult, teratoma with malignant transformation may be cured by multidisciplinary treatment based on histopathology.
