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

Various adverse reactions to COVID-19 vaccination have been reported; however, no case reports have focused on dysphagia. We herein present two cases of severe dysphagia after COVID-19 vaccination. Case 1: A 24-year-old man with Burkitt's lymphoma developed dysphagia and multiple cranial nerve palsies. Case 2: An 80-year-old man with Parkinson's disease developed aspiration pneumonia and dysphagia. Both patients underwent a detailed dysphagia evaluation and swallowing rehabilitation. According to the Vaccine Adverse Event Reporting System, dysphagia following COVID-19 vaccination is very rare. Clinicians should be aware of the appearance or worsening of dysphagia following COVID-19 vaccination.
