Yolk sac tumor of the fourth ventricle in a 3-year-old boy: imaging features.
Article in Child's nervous system : ChNS : official journal of the International Society for Pediatric Neurosurgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeYolk sac tumor (YST) is a rare malignant germ cell tumor and typically occurs in gonads. It is extremely rare in the brain, especially in the fourth ventricle.
methodsThis study reported the case of a 3-year-old boy with intermittent vomiting for 11 days and then intermittent twitch for 5 h.
resultsBrain computed tomography showed a slightly higher density mass in the fourth ventricle. Brain magnetic resonance imaging showed an irregular lobulated expansive mass in the fourth ventricle, appearing with the low intensity on T1-weighted images, and uneven hyperintensity on T2-weighted images. The enhanced scan showed inhomogeneous and strong enhancement, with multiple small cyst-like areas of no enhancement. Tortuous tumor vessel also can be seen. The pathological results after surgical resection showed an YST in the fourth ventricle.
conclusionWhen a mass is observed in the fourth ventricle in children, with uneven signal with hemorrhage and cystic change, inhomogeneous and strong enhancement, and facilitated diffusion on diffusion-weighted imaging, YST should be considered. The increase of α-fetoprotein value can help differential diagnosis.
