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

backgroundHemiballismus is a rare movement disorder characterized by violent, involuntary movements, usually resulting from a stroke affecting the subthalamic nucleus. Risperidone, an atypical antipsychotic, has shown effectiveness in managing these symptoms. CASE PRESENTATION: We present the case of a 75-year-old Asian female patient of Cambodian origin with hemichorea-hemiballismus secondary to a subacute hemorrhage in the left basal ganglia, in the context of essential thrombocythemia. The patient responded remarkably well to risperidone. The patient's story, along with video documentation of her condition and response to treatment, is discussed.

conclusionThis case highlights the potential of risperidone in treating hemichorea-hemiballismus, providing a nonsurgical option for managing this debilitating condition.
