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
purposeEndoscopic arytenoid abduction lateropexy (EAAL) is a reliable, minimally invasive technique for treating bilateral vocal fold palsy (BVFP). This study aimed to evaluate the safety and functional efficacy of a modified approach for EAAL that utilizes absorbable sutures and CO₂-laser para-arytenoid soft tissue reduction to achieve durable lateralization without the long-term use of foreign materials.
methodsThis study enrolled 15 patients with permanent BVFP following thyroid surgery, including 8 revisions after prior glottis-widening procedures. The technique involved temporary arytenoid fixation with an absorbable suture after soft tissue reduction and, when required, cricoarytenoid joint disarticulation. Peak inspiratory flow (PIF), maximum phonation time (MPT), Voice Handicap Index (VHI), and laryngeal function-specific quality-of-life (QoL) were assessed before and 1 and 12 months after surgery. Deglutition function was evaluated with fiberoptic endoscopic evaluation of swallowing (FEES) and the MD Anderson Dysphagia Inventory (MDADI) questionnaire.
resultsAll patients immediately achieved a stable and durable airway without perioperative complications. Mean PIF increased significantly after surgery and remained stable at 12 months. MPT showed no significant change at either postoperative timepoint. VHI improved significantly throughout follow-up. MDADI scores improved early and remained significantly above baseline. QoL improved markedly in the early postoperative period and remained significantly increased at 12 months. FEES revealed physiological swallowing in 13/15 patients. Suture-related symptoms resolved after suture absorption.
conclusionThe modified EAAL with soft tissue reduction provides a stable airway while maintaining phonatory and swallowing functions. Temporary fixation ensures durable lateralization via paraglottic scarring, thereby minimizing long-term foreign body-related morbidity.
