Laryngeal Dysfunction Following COVID-19: A TriNetX Retrospective Cohort Study.

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(S): Long COVID affects multiple organ systems, yet the incidence and risk factors for post-COVID-19 laryngeal dysfunction remain underexplored. This study evaluated the incidence of laryngeal dysfunction following COVID-19.
methodsA retrospective cohort study was performed using the TriNetX Global Collaborative EHR Network (> 180 million records). Adults without prior laryngeal dysfunction or major comorbidities were stratified by COVID-19 exposure and compared with uninfected controls. Outcomes included chronic cough, dysphagia, voice disorders, vocal fold paralysis, and laryngeal spasm, assessed up to 5 years post-infection. After propensity score matching, odds ratios (OR) and risk differences (RD) with 95% confidence intervals (CI) were calculated.
resultsCOVID-19 was associated with significantly increased odds of chronic cough (peak OR 7.12; RD 0.33%, p < 0.0001), dysphagia (peak OR 2.71; RD 0.36%, p < 0.0001), voice disorders (peak OR 3.25; RD 0.12%, p < 0.0001), vocal fold paralysis (peak OR 2.17; RD 0.01%, p < 0.0001), and laryngeal spasm (peak OR 2.79; RD 0.003%, p < 0.0001). Incidence peaked at 1-2 years for most outcomes and at 2-3 years for laryngeal spasm. Hospitalization and mechanical ventilation were associated with increased rates of dysphagia (HR 2.63; HR 5.26), voice disorders (HR 1.15; HR 4.45), and vocal cord paralysis (HR 2.09; HR 9.35), but reduced rates of chronic cough (HR 0.68; HR 0.45). Vaccinated patients showed higher rates of chronic cough (HR 1.36) and voice disorders (HR 1.22).
conclusionCOVID-19 is associated with increased incidence of new-onset laryngeal dysfunction, most commonly peaking 1-2 years after infection and influenced by hospitalization, mechanical ventilation, and vaccination status. LEVEL OF EVIDENCE: 3:
