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

Background: Dysphagia is a potentially fatal symptom of Parkinson's disease (PD) and is characterized by frequent silent aspiration, a known risk factor for aspiration pneumonia. A previous study has reported that the dopamine agonist rotigotine (levodopa equivalent dose of 60 mg/day) delivered via transdermal patch improves swallowing function more effectively than oral levodopa (200 mg/day), highlighting the importance of continuous dopaminergic stimulation (CDS) in managing dysphagia. To achieve CDS, patients with advanced PD may require device-assisted therapies (DATs), including levodopa-carbidopa intestinal gel (LCIG), which have significantly improved swallowing function on some measures. In contrast, swallowing function is an important prognostic factor for patients with PD undergoing LCIG. Continuous subcutaneous infusion of foslevodopa/foscarbidopa (CSCI-FF) is a newly developed DAT; however, its effect on swallowing function remains unknown. Methods: This retrospective open-label evaluator-blinded study included seven patients with PD. Swallowing function was assessed using videofluoroscopic swallow studies (VFSS) conducted before and after initiating CSCI-FF. Evaluations included the Japanese Swallowing Scale, the Dysphagia Outcome and Severity Scale (DOSS), Penetration/Aspiration Scale, oral transit time (OTT), and pharyngeal transit time (PTT). Results: Following the introduction of CSCI-FF, results of VFSS showed significant improvement in the total score of the Japanese swallowing scale, OTT, and PTT. Conclusions: This study provides preliminary evidence that CSCI-FF may partially improve swallowing function in patients with advanced PD. Further research with larger cohorts is warranted.
