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

objectiveGlobus pallidus internus deep brain stimulation (GPi-DBS) is an established treatment for dystonia, but its specific efficacy for tardive dystonia (TD) remains insufficiently documented. To evaluate the long-term clinical outcomes of GPi-DBS and to identify optimal stimulation sites in patients with medically refractory TD.

methodsWe retrospectively analyzed data from 26 patients with TD who underwent bilateral GPi-DBS. Clinical outcomes were assessed using the Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS). Optimal stimulation sites were identified using voxelwise sweet spot analysis.

resultsAt an average follow-up time of 42 months (range 12-4 months), the mean BFMDRS score improvement was 81.5%. The optimal stimulation sites were located in the posteroventral region of the GPi. Two patients experienced sustained symptom remission after DBS cessation. Complications included device-related infection (n=2), dysarthria (n=4), and gait imbalance (n= 1); no severe permanent complications occurred.

conclusionGPi-DBS is effective and safe for patients with medically refractory TD, providing significant long-term symptom relief. The optimal stimulation sites were located in the posteroventral GPi, which is consistent with those reported for patients with other dystonia types.
