Injection Laryngoplasty on Cough Strength and Swallowing Safety in Treating Glottal Insufficiency.

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
ImportanceGlottal competence and cough effectiveness are associated with aspiration. In unilateral vocal fold paralysis (UVFP), injection laryngoplasty (IL) is the mainstay treatment for those with dysphonia and dysphagia. However, few data exist explaining how IL exerts its effects on aspiration prevention.ObjectiveTo evaluate the effect of IL on voluntary cough strength, glottal closure, and swallowing function. Furthermore, the effects were compared between patients with active treatment/disease and those without.Study DesignProspective cohort study.SettingLaryngology clinic of single tertiary hospital.ParticipantAdult patients underwent IL for UVFP between January 2021 and April 2023.Main Outcome MeasuresMaximum volitional cough pressure (MCoughP) was quantified before and after IL, as well as clinical voice outcomes and normalized glottal gap area. For those with a complaint of aspiration, the Eating Assessment Tool (EAT-10) questionnaire and Penetration-Aspiration Scale (PAS) were also evaluated.ResultsForty-one patients were included (26M:15F; age range 32 to 80 years old, mean age 58.7). Clinical voice outcomes and glottal closure were significantly improved in all patients, as well as EAT-10 score (16.22 ± 11.83 at pre-IL and 10.83 ± 11.17 at post-IL,
