Osteosarcoma in a Young Patient: When the Tumor Reaches the Heart.
Article in JACC. Case reports, 2026. 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
backgroundCardiac metastases from osteosarcoma are exceedingly rare and often diagnosed late, representing a major diagnostic challenge. CASE SUMMARY: A 17-year-old boy with a history of osteosarcoma presented with dyspnea and palpitations. Transthoracic echocardiography revealed a mobile intracardiac mass attached to the tricuspid subvalvular apparatus with partial right ventricular outflow tract obstruction. Cardiac magnetic resonance demonstrated a lesion with heterogeneous signal intensity and late gadolinium enhancement, suggestive of malignancy. Surgical resection was performed, and histopathology confirmed metastatic osteosarcoma. DISCUSSION: This case highlights the importance of multimodality imaging in the evaluation of intracardiac masses and underscores the need to consider cardiac metastasis in patients with advanced malignancy and atypical cardiac symptoms.
