Prevalence and Risk Factors for Swallowing Dysfunction in Patients With Laryngomalacia Treated Medically and Surgically.

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
Objective: To identify the prevalence, pattern, and nature of swallowing dysfunction (SwD) in a consecutive cohort of patients with laryngomalacia (LM), and to determine factors associated with a higher burden of SwD. Study Design: This was a retrospective review of consecutive patients diagnosed with LM by 2 pediatric otolaryngologists between 2013 and 2022 and a minimum of 3-month follow-up. Setting: Tertiary care pediatric otolaryngology referral center. Methods: Consecutive cohort of patients less than 3 years old with LM diagnosed on flexible laryngoscopy were reviewed. Patients with incomplete follow-up, lack of swallowing assessment, and genetic conditions or syndromes were excluded. All patients underwent at minimum a systematic clinical swallowing evaluation by a speech-language pathologist specialized in pediatric dysphagia. Patients with concerning clinical exams underwent instrumental swallow evaluation (Videofluoroscopic Swallow Study [VFSS] or Flexible Endoscopic Evaluation of Swallowing [FEES]). The prevalence of abnormalities of clinical swallowing evaluation, instrumental swallow evaluation data, and details of management were collected. Results: Two hundred and twelve patients met criteria and were included in the final analysis. One hundred and fifteen patients (54%) had an instrumental assessment (VFSS or FEES). Of the instrumental assessments performed, 96 (69%) were abnormal. Of the total patient cohort, 55 (26%) had laryngeal penetration and/or aspiration. One hundred and seventeen (55%) had clinical or instrumental indications for intervention, with 18 (8%) requiring tube feeding. Patients with severe LM and those treated surgically had a statistically significant higher rate of penetration and aspiration. Conclusion: Patients with LM have a high burden of dysphagia requiring medical intervention. The authors advocate for routine and systematic assessment of all patients with LM for swallowing dysfunction.
