Abnormal Swallowing Characteristics in COVID-19 Patients.
Article in Dysphagia, 2025. 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
This study aimed to characterize the abnormal swallowing features observed during Videofluoroscopic Swallowing Studies (VFSS) in moderate to severe COVID-19 patients. From the JH CROWN cohort database (January 2020 to March 2022), a total of 3,660 patients with moderate to severe COVID - 19 disease requiring oxygen supplementation were identified. The study abstracted and reported VFSS referral rates and swallowing characteristics using Modified Barium Swallow Impairment Profile (MBSImP). 16% (n = 588) of patients exhibited dysphagia; only half underwent VFSS. Among those referred, 39.3% had COVID-19 severity level 7, 39% exhibited aspiration, and 30% had silent aspiration. Abnormal MBSImP scores were reported in the following components: tongue control during bolus hold (score 2/3, 40%), bolus transport and lingual motion (score 3/4, 34%), oral residue (score 2/4, 57.7%), initiation of pharyngeal swallow (score 3/4, 65.2%), laryngeal vestibular closure (score 1/2, 64.5%), and pharyngeal residue (score 2/4, 50.5%). In conclusion, this large cohort of COVID-19 patients exhibited a myriad of swallowing abnormalities in the oral and pharyngeal phases, with a notably high rate of silent aspiration. Moreover, differentiating COVID-19-induced dysphagia from post-extubation dysphagia is challenging.
