A large primary leiomyoma of right ventricle in a 4-year-old child: case report.
Article in Frontiers in cardiovascular medicine, 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
Background: Cardiac leiomyomas are extremely rare cardiac anomalies. Among them, primary leiomyomas confined to heart are even rarer, which have been reported only in few cases. Once diagnosed, surgical resection is the most common choice for treatment. Case summary: A 4-year-old girl with heart murmur was diagnosed with a large spherical mass which was located in the right ventricle. The oval mass measured approximately 50 × 40 mm and caused obstruction of the right ventricular outflow tract. To relieve the obstruction, the large mass was resected in surgery. During the surgery a 45 × 40 × 35 mm oval structure with stiff elastic consistence was found being attached to the free wall of the right ventricle. No other abnormalities like regurgitation were detected. Histopathological examination of the resected mass indicated a benign leiomyoma. Postoperative recovery was uneventful. Discussion: As a benign cardiac tumor, leiomyoma is exceptionally rare. The majority of cardiac leiomyomas are metastatic. Primary ones are few. Imaging and histologic examination can help to diagnose. After surgical resection, most patients can recover well.
