Comparison between dysphagia aortica and dysphagia after cardiac surgery using videofluoroscopic swallowing studies.
Article in BMC surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundDysphagia aortica (DA) and dysphagia after cardiac surgery (DACS) are principally classified as esophageal dysphagia. The purpose of this study was to compare the swallowing dysfunction of DA and DACS patients using videofluoroscopic swallowing studies (VFSS).
methodsData of patients diagnosed with DA or DACS who had undergone VFSS were reviewed retrospectively. Twenty-two patients with DA and ten patients with DACS were included, and Penetration–Aspiration Scale (PAS), Functional Dysphagia Scale (FDS), and esophageal transit time (ETT) were assessed.
resultsSwallowing impairment in oral and pharyngeal phases shown by PAS and FDS scores did not differ between the two groups. ETT was extended in two groups, and the pure aortic segment time was significantly delayed in the DA patients only (P = 0.045).
conclusionsCompared with healthy individuals in previous studies, both groups showed normal PAS and higher FDS scores, and longer ETT. Both the DA and DACS patients had some oropharyngeal and prominent esophageal dysphagia. Further studies are needed to determine the extent of changes by performing preoperative and postoperative VFSS in patients with aortic or cardiac diseases scheduled for elective, non-emergency surgery.
