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
Purpose: Pseudomembranous Aspergillus tracheobronchitis (PMATB), an uncommon clinical form of invasive aspergillosis, is mainly occurs in patients who are moderate to severely immunocompromised. There are some case reports of immunocompetent individuals developing invasive aspergillosis after occupational exposure (Primarily observed in farmers, sawmill workers, waste collectors, mushroom processing workers, or those who handle grain, hay, or straw), including allergic bronchopulmonary aspergillosis (ABPA), severe asthma with fungal sensitization, hypersensitivity pneumonitis, and invasive pulmonary aspergillosis. To our knowledge, there are no published case reports in the literature with PMATB as the main presentation in construction worker after occupational exposure. Case Presentation: We report a case of a 45-year-old construction worker who was previously healthy, presented with cough for one weak and dyspnea and wheezing for two days. Computed tomography (CT) of the chest was normal. He was misdiagnosed with severe asthma, and started on intravenous corticosteroids, together with an inhaled short-acting beta2 agonist and inhaled muscarinic antagonist and empirical anti-infective therapy. However, his symptoms were still progressing. Bronchoscopy revealed cream-colored plaques throughout the trachea and bronchial mucosa. Photomicrograph of tissue and culture of post-bronchoscopy sputum and bronchial aspirate showed aspergillus with branching and septate hyphae. Results: The patient recovered quickly when treated systemically with voriconazole. Conclusion: Our report presents an immunocompetent construction worker with no chronic diseases who developed invasive aspergillosis primarily manifesting as PMATB due to occupational exposure. This presentation is rare and has not been previously documented in the literature. Early diagnosis and prompt initiation of antifungal therapy may improve the outcome and decrease mortality rate.
