1 · What the graph read from it

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.

2 · The registry

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

Hamartoma of the floor of fourth ventricle (HFFV) is an extremely rare entity known to be causing focal movement disorders in children. According to the few reported cases in literature, the only effective treatment is disconnection or resection of the lesion which can be very challenging in this anatomic area. We report a 15-year-old child with a fourth ventricle floor's limited nonexophytic hamartoma revealed by brief paroxysmal movement disorder episodes since the age of 5 months, without EEG correlate. He was treated for the first time by safe surgical electrophysiology-guided resection, with promising results on epileptic disease. This positive result opens interesting prospects for improving the surgical management of other lesions affecting this anatomical region, while limiting postoperative neurological deficits.
