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

backgroundAnticholinergic medications and botulinum neurotoxin injections are established treatments for dystonia, yet they carry potential side effects and practical challenges. Deep brain stimulation (DBS) is offered in case of poor response to these approaches.

objectivesTo assess the need for anticholinergic medications and botulinum neurotoxin injections in adult and pediatric patients at two specialized Canadian centers before and after DBS over the past 10 years.

methods58 patients were included analyzing data before, 6 and 12 months after DBS. Clinical assessment included the Toronto Western Spasmodic Torticollis Rating Scale and Fahn-Marsden Dystonia Rating Scale. Anticholinergic burden was determined by the Anticholinergic Drug Scale (ADS).

resultsSeverity of cervical dystonia and ADS scores reduction were statistically significant after DBS. Anticholinergic medication and Botulinum Neurotoxin injections were discontinued a year after surgery in 28.8% and 72.4% of the patients, respectively.

conclusionSimplification of anti-dystonia treatments is another added benefit of DBS.
