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

Background: Bobble-head doll syndrome (BHDS) is a rare movement disorder usually observed in children and associated with third ventricular lesions or hydrocephalus. Case report: A 24-year-old man presented with progressive memory impairment, gait instability, urinary incontinence, and irregular no-no head tremor with a sensory trick. MRI revealed severe obstructive hydrocephalus due to an aqueductal web. Ventriculoperitoneal shunting was performed, and the tremor resolved within one week. Neurological symptoms improved, and he remained independent 18 months after surgery. Discussion: Adult BHDS is extremely rare. Early recognition and appropriate CSF diversion can provide favorable outcomes.
