Long-Term Outcomes of Deep Brain Stimulation in Woodhouse-Sakati Syndrome.

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.
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
backgroundWoodhouse-Sakati syndrome (WSS) is a rare autosomal recessive disease with distinctive neuroendocrine manifestations, with dystonia being the most common. No clear guidelines are available for the treatment of dystonia in WSS.
objectiveThe aim was to analyze the impact of deep brain stimulation (DBS) on WSS-associated dystonia.
methodsPatients with genetically confirmed WSS who underwent globus pallidus internus (GPi) DBS for dystonia were analyzed retrospectively. The participants were assessed using the Burke-Fahn-Marsden Dystonia Rating Scale (BFMDRS) and were videotaped pre- and post-surgery at multiple follow-up points. The primary outcome was the BFMDRS score at 1 year post-surgery, compared with baseline. The primary outcome was correlated with preoperative factors, including age at onset, disease duration at surgery, proportion of life lived with dystonia, and severity rate.
resultsFive patients with severe progressive generalized dystonia secondary to clinically and genetically confirmed WSS underwent bilateral GPi DBS from February 2011 through September 2023. The mean age at disease onset and at the time of DBS was 11.3 and 18.6, respectively. All patients' BFMDRS total scores improved from baseline to 12 months post-DBS. The mean pre-DBS BFMDRS score was 71.1, and the mean post-DBS BFMDRS score was 43.6. The percentage improvement in the BFMDRS mean score from pre- to post-DBS was approximately 39%.
conclusionsOur case series showed clinical improvement in patients who underwent bilateral GPi DBS as an advanced therapy for generalized dystonia secondary to WSS. We recommend further research on DBS in a larger sample of WSS patients to obtain significant results. © 2026 The Author(s).
