The Diagnostic Utility of Bronchoalveolar Lavage in Pulmonary Infections:
Article in Sultan Qaboos University medical journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives: Bronchoalveolar lavage (BAL) is an important diagnostic tool. Despite advancements in microbiological strategies, BAL's yield remains inconsistent. Hence, this study aimed to evaluate the yield of BAL in terms of microbial detection and correlate these results with computed tomography (CT) findings and antimicrobial usage duration before bronchoscopy. Methods: This retrospective cohort study included all adult patients who underwent bronchoscopy with BAL at Sultan Qaboos University Hospital, Muscat, Oman, from January 2021 to December 2022. Results: A total of 203 patients underwent bronchoscopy. The primary indication for bronchoscopy was lung infiltrates in patients with haematological malignancies (49.3%). The overall BAL yield was 58.1%. All immunocompromised patients with a halo sign on CT scans had negative BAL galactomannan (GM) results ( Conclusion: This study revealed a BAL diagnostic yield of 58.1%, aligning with existing literature. Performing BAL on both lungs may enhance this yield. No correlation was found between the CT findings and BAL GM results. The study highlights the importance of early BAL intervention before antimicrobial usage.
