Combined pathogenic characteristics to analyze susceptibility factors of postoperative pneumonia in patients undergoing cardiac surgery.
Article in Journal of cardiothoracic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
Postoperative infection prevention is crucial for cardiac surgery patients. This study enrolled 579 cardiac surgery patients from November 2021 to July 2022, reporting a 12.3% incidence of postoperative pneumonia. Blood sugar, Montreal Cognitive Assessment (MoCA) scores, respiratory failure, and complications were linked to respiratory infections. Significant differences in biomarkers, including creatine kinase, urine volume, alanine transaminase (ALT), hemoglobin, and PaO2/FiO2, were observed between pneumonia types. Bacterial pneumonia cases showed positive correlations between ALT, urine volume, and infection, while hemoglobin and PaO2/FiO2 correlated negatively. The most common pathogens were Klebsiella pneumoniae (20.3%), Acinetobacter baumannii (11.6%), and Pseudomonas aeruginosa (10.9%). Identifying susceptibility factors and pathogenic characteristics can guide effective prevention strategies. Monitoring and oxygen therapy remain essential for reducing postoperative pneumonia risk in cardiac surgery patients.
