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
Background: Airway obstruction due to tumor invasion or concurrent respiratory distress and hemoptysis poses a significant challenge in clinical management, often requiring prompt and effective intervention to alleviate symptoms and improve patient outcomes. This study aimed to evaluate the efficacy and safety of selective transcatheter arterial embolization (TAE) as a preparatory measure to mitigate airway obstruction before bronchoscopic debulking as an approach to address this clinical challenge. Methods: The data of patients with airway obstruction due to tumor invasion or concurrent respiratory distress and hemoptysis treated at The First Affiliated Hospital of Zhengzhou University from January 2018 to August 2022 were analyzed. After computed tomography (CT) scans and bronchoscopic findings were assessed, selective TAE was performed as a preparatory measure to alleviate airway obstruction before bronchoscopic debulking, and the occurrence of hemorrhage-related complications, Karnofsky Performance Status (KPS) score, breathlessness index, and the extent of airway obstruction were evaluated. Results: All 22 patients underwent selective TAE before bronchoscopic tumor debulking. The overall efficacy rate was 100%, with a significant improvement in the KPS score from preoperative (60.45±14.63) to postoperative (74.55±9.63) levels (t=-6.891; P<0.001). Similarly, there was a considerable reduction in the shortness of breath score from preoperative (2.91±0.81) to postoperative (1.73±0.63) levels (t=6.973; P<0.001). Airway obstruction decreased substantially from preoperative (79.14%±14.56%) to postoperative (21.27%±7.19%) levels (t=26.857; P<0.001). Furthermore, the severity classification of airway obstruction decreased from preoperative (4±0.82) to postoperative (1.36±0.49) levels (t=18.794; P<0.001). Among the patients, only one experienced moderate bleeding necessitating prolonged mechanical balloon compression and intracavitary lesion removal, while the other patients had minor and negligible bleeding. Conclusions: TAE combined with endoscopic debulking can effectively control intraoperative bleeding and respiratory distress and achieve successful local resolution of endotracheal hypervascular tumors.
