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

background22q11.2 deletion syndrome (22q11DS) is a multisystem genetic disorder associated with a significantly increased risk of early-onset Parkinson's disease (EOPD). Management is challenging because psychiatric and cognitive comorbidities often limit advanced therapies such as deep brain stimulation (DBS). CASES: We report 2 patients with 22q11DS who developed EOPD at about age 30 with prominent psychiatric manifestations. In both cases, diagnosis of 22q11DS was delayed until genetic testing was performed for atypical parkinsonism associated with intellectual disability and dysmorphic features. Severe motor fluctuations and dyskinesia developed early. Because of psychiatric vulnerability, DBS and dopamine agonists were considered unsuitable. Continuous intrajejunal levodopa-carbidopa infusion (LCIG [levodopa-carbidopa intestinal gel]) was initiated, which led to sustained improvement in motor fluctuations and functional status, although individualized dose adjustments were required.

conclusionsLCIG may represent a valuable therapeutic option in selected patients with 22q11DS-associated Parkinson's disease when psychiatric comorbidity limits other advanced therapies.
