1 · What the graph read from it

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.

2 · The registry

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

Introduction: Mounier-Kuhn syndrome (MKS) is a rare tracheobronchial disorder with fewer than 500 reported cases globally. This report describes an asymptomatic MKS patient diagnosed incidentally due to unexplained intraoperative airway leakage during general anesthesia, highlighting the challenges in airway management. Case presentation: A 78-year-old male with tracheal dilation (transverse/sagittal diameters: 28.2/50.2 mm) underwent laparoscopic hernia repair. Severe airway leakage occurred despite standard intubation, resolved by dynamic endotracheal tube repositioning and cuff pressure optimization. Conclusions: Anesthesiologists often focus more on airway narrowing and lack vigilance regarding airway dilation, This case emphasizes the importance of recognizing MKS in unexplained airway leaks and demonstrates effective intraoperative adjustments for ventilation security.
