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

Dystonia is a movement disorder characterized by sustained or intermittent muscle contractions resulting in abnormal movements and postures. DYT-THAP1 is one of the most frequent genetic causes of generalized dystonia and may present with characteristic clinical features that help guide diagnostic suspicion before molecular confirmation. We report a 58-year-old man who developed dysphagia and dysarthria at 22 years of age, followed by progressive dystonic posturing involving the upper limbs, face, neck, and lower limbs. Family history revealed a similar condition in his father. Neurological examination demonstrated generalized dystonia with marked cranio-cervical and bulbar involvement. Brain magnetic resonance imaging and extensive metabolic and autoimmune investigations were unremarkable. Given the clinical presentation and family history, a genetic etiology was suspected. A dystonia gene panel identified a variant in the THAP1 gene, NM_018105.3:c.108G > T (p.Trp36Cys), establishing the diagnosis. Cranio-cervical involvement and prominent bulbar symptoms may represent important clinical clues suggesting DYT-THAP1 in patients with generalized dystonia, highlighting the importance of careful phenotypic characterization.
