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
objectiveThis study aimed to investigate the relationship between bronchoalveolar lavage (BAL) cellular profiles, microbiological status, and clinical outcomes such as hospital admission in adult patients with non-cystic fibrosis bronchiectasis.
methodsA retrospective cross-sectional study was conducted on thirty adult bronchiectasis patients. Demographic, clinical, and laboratory data were collected. The cellular components of BAL fluid (macrophages, neutrophils, lymphocytes, and eosinophils) were analyzed. Patients were grouped according to the presence of microbial culture growth and history of hospitalization in the past year. Statistical analyses were performed to determine significant relationships.
resultsThe median age was 57 years, and the gender distribution was equal. There was no significant difference in BAL cellular profiles between groups with and without culture growth. However, in the group with a hospital admission in the past year, BAL showed a significantly lower percentage of alveolar macrophages (20% vs. 47%,
conclusionsBAL cellular analysis provides valuable information beyond routine microbiological investigations in bronchiectasis. The low-alveolar-macrophage and high-eosinophil profile was found to be significantly associated with hospitalization, and this profile has the potential to serve as a prognostic biomarker in defining the "high-risk" phenotype. These findings highlight the complexity of the local inflammatory response and reveal the potential role of BAL in developing personalized treatment strategies for patients with bronchiectasis.
