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
backgroundCentral Airway Obstruction (CAO) presents a significant challenge in both malignant and benign conditions, requiring urgent intervention. Traditional debulking methods have limitations, prompting the exploration of alternative techniques like the microdebrider, initially used in otolaryngology. Our study, assesses the safety and efficacy of the microdebrider in managing CAO.
methodsThis prospective, non-randomized interventional study included patients with CAO treated using the microdebrider during therapeutic bronchoscopy between February 2023 and January 2024. Data collected included patient demographics, obstruction characteristics, procedural time, and adverse events. The microdebrider was introduced via a rigid bronchoscope, and additional techniques like APC and electrocautery were employed as needed. Five historical control cases were analyzed for comparison.
resultsAmong 21 cases, 71% were malignant, primarily non-small-cell lung cancer (52.4%). Severe obstructions (>70%) were present in 81% of cases. Post-debulking, the mean obstruction reduced to less than 10%, with 76% categorized as insignificant. The mean procedure time was 28 minutes, with no adverse events observed. Compared to historical controls, microdebrider procedures were faster (28 vs. 51.2 minutes), with lower residual obstruction (10% vs. 20%).
conclusionsThe microdebrider is an effective and economical tool for rapidly re-canalizing severely obstructed airways, particularly in broad-based tumors. It offers advantages over traditional methods, including shorter procedural times and fewer complications. Our study supports the microdebrider's relevance in managing CAO, especially in resource-limited settings.
