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

objectiveThis study aimed to characterize the phenotypic spectrum and therapeutic outcomes of patients of Indian and Asian origin with DYT-TOR1A.

methodsA retrospective chart review of patients with genetically confirmed DYT-TOR1A (c.907_909delGAG; p.Glu303del variant) from a tertiary care center in India.

resultsTwelve patients (11 males, 91.7%) with a median age at disease onset of 10.5 years (range, 8-17 years) and a disease duration of 5 years (range, 2 months-31 years) were included. All patients had an isolated and progressive dystonia phenotype. Eight patients (66.7%) had a disease onset in childhood, and limb involvement at disease onset was noted in 10 (83.3%) patients. Five patients (41.7%) underwent bilateral globus pallidus internus deep brain stimulation within a median duration of 4 years (range, 2.5-6.5 years) from onset, with significant improvement.

conclusionThis Indian patient cohort showed a strong male predominance and consistent early involvement of the upper limbs. A shorter disease course accompanied by greater severity highlights the need for early recognition and potential surgical intervention.
