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

ObjectiveParkinson's disease (PD) frequently involves dysphagia, yet real-world longitudinal data capturing its progression and response to clinical care remain limited. Most prior studies exclude treated patients or rely solely on subjective or cross-sectional data. This study investigates long-term changes in swallowing physiology and diet in a pragmatic, treated PD population.MethodsWe retrospectively reviewed patients with PD who underwent at least two videofluoroscopic swallow studies (VFSS) ≥ 1 year apart at a tertiary laryngology center. Individuals with comorbid neurologic or structural disease were excluded. Standardized metrics included the Dynamic Imaging Grade of Swallowing Toxicity (DIGEST), Penetration Aspiration Scale (PAS), Functional Oral Intake Scale (FOIS), and International Dysphagia Diet Standardization Initiative (IDDSI), with kinematic analysis of Pharyngeal Constriction Ratio (PCR) and Maximum Pharyngoesophageal Segment Opening (PESmax). Ordinal outcomes were compared using Wilcoxon signed-rank tests; kinematic changes were analyzed with paired
