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

We experienced a young patient who presented with progressive parkinsonism and cerebellar ataxia. Brain magnetic resonance imaging revealed progressive brain calcification, expanding from the bilateral basal ganglia to the central pons, caused by a delayed reaction to the radiation therapy that she had received to treat craniopharyngioma 14 years earlier. Heterogeneous clinical symptoms due to radiation-induced brain calcification have been described, but parkinsonism has never been reported. While dopamine transporter-single photon emission computed tomography revealed only slight damage to the dopaminergic striatal pathway, the extension of calcification to the periventricular white matter was likely responsible for her parkinsonism.
