Micro-Computed Tomography Based Whole Block Imaging of Asthma-Associated Airway Remodeling With Mycobacterium avium-Induced Cavity Formation: 3-Dimensional Nondestructive Analysis.

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
Asthma is a recognized risk factor for nontuberculous mycobacterial (NTM) pulmonary infections, yet the precise routes of infection and dissemination remain visually unclear. We analyzed a rare surgical case of asthma complicated by Mycobacterium avium-associated lung cavity formation in a young adult. Following antibiotic treatment, the patient underwent left upper segmentectomy, with successful subsequent treatment of residual lesions using amikacin liposome inhalation suspension. To precisely visualize the infection route, we utilized a three-dimensional merged whole block imaging (WBI) technique. Fifteen formalin-fixed paraffin-embedded tissue blocks from the resected lung were individually scanned using a custom-built micro-computed tomography system, reconstructed, and combined to generate merged-WBI. Three core merged-WBIs revealed that the remodeled asthma-associated airway ascended from the proximal hilar region, intertwined with surrounding epithelioid granulomatous tissue, and then descended into a subpleural cavity composed of epithelioid granulomas with central caseous necrosis containing acid-fast bacilli. Besides the distinct airway path, the WBI delineated the distribution of minor epithelioid granulomas and calcifications. This report provides the first three-dimensional visualization of a continuous airway route extending from the hilum to a subpleural cavity using merged-WBI, suggesting bronchial spread as a probable mechanism of NTM dissemination in the setting of chronic airway disease. Clinical trial registration: No clinical trials.
