Unusual co-occurrence of hypertrophic inferior olivary degeneration with infratentorial cavernomatosis and orbital cavernous hemangioma.

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
Hypertrophic olivary degeneration (HOD) is a rare condition resulting from a lesion in the Guillain-Mollaret triangle (GMT), causing transsynaptic degeneration and hypertrophy of the inferior olivary nucleus (ION). The GMT is composed of the dentate nucleus, red nucleus, and ION, and is commonly affected by ischemic and hemorrhagic strokes, vascular malformations, neoplasms, or surgical trauma. Cavernomas are a frequent type of cerebral vascular malformation associated with HOD, while orbital cavernous hemangiomas are another rare vascular malformation. The association of these two malformations is scarcely reported, with only one case previously documented. We report the case of a 26-year-old male presenting with right exophthalmos and palatal myoclonus, where brain MRI demonstrated HOD secondary to infratentorial cavernomatosis, along with a right orbital cavernous hemangioma. This case highlights a rare co-occurrence of infratentorial cavernomatosis and orbital cavernous hemangioma, emphasizing the importance of recognizing vascular malformations as potential causes of HOD.
