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

backgroundThe effectiveness of pharmacological treatment on dysphagia in Parkinson's disease (PD) is debatable. We reviewed the literature for analyzing the effect of pharmacological treatment on the improvement of dysphagia in PD patients.

methodsWe searched the PubMed database for papers published before June 21, 2020, that evaluated the effect of pharmacologic treatments for improving dysphagia in patients with PD. The following inclusion criteria were applied for the selection of articles: 1) studies performed on patients with dysphagia due to PD, 2) studies where pharmacologic treatment was applied for improvement of dysphagia, and 3) those where follow-up evaluation was performed after the treatment.

resultsThe primary literature search yielded 415 relevant papers. After reading their titles and abstracts and assessing their eligibility based on the full-text articles, we finally included nine studies in this review. In five previous studies, the positive effects of dopaminergic drugs on dysphagia were reported, whereas two showed no significant positive results. The remaining two studies showed equivocal results.

conclusionWe found that dopaminergic drugs have some potential to improve dysphagia in patients with PD. However, studies with high-quality evidence are lacking. For the clear elucidation of the effect of dopaminergic drugs on dysphagia in patients with PD, randomized controlled trials with large cohorts and detailed analyses should be conducted in the future.
