Recurrent Laryngeal Nerve Stretching in Tracheal Diverticulum: First Documented Mechanism of Hoarseness and Systematic Review of Literatures.

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
Tracheal diverticulum is a rare paratracheal air cyst. It is often asymptomatic. Large symptomatic cases may compress the recurrent laryngeal nerve (RLN) and cause hoarseness. It is a rare presentation, in < 0.2 cases per year in the world. We present a 45-year-old woman that had 6 months of chronic cough, dysphagia, odynophagia, dyspnea, hoarseness, hemoptysis, choking, and neck pain. She was not a smoker. Spirometry showed mild obstruction pattern (FEV1 78%). CT with 3D reconstruction revealed a 4 × 5 cm right posterolateral tracheal diverticulum (fifth-seventh rings, 8 mm communication). Bronchoscopy confirmed limited right vocal cord mobility. We did an open cervical excision that preserved the RLN. Histopathology confirmed acquired diverticulum. Hoarseness resolved in 3 weeks; repeat bronchoscopy showed normal vocal cord mobility. 3-month CT confirmed resolution; 1-year FEV1 improved. Asymptomatic at 12 months. Systematic review (1998-2025) found 4 prior hoarseness cases (total
