Risk factor identification and prediction of pleural effusion following coronary artery bypass grafting.
Article in American journal of translational research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveTo evaluate the incidence of pleural effusion (PE) following coronary artery bypass grafting (CABG), identify associated risk factors, and develop a validated predictive model for early detection.
methodsA retrospective cohort of 1,979 patients who underwent CABG at Beijing Chaoyang Hospital (Capital Medical University) was randomly divided into training (70%) and validation (30%) sets. Risk factors for PE were identified through univariate analysis, LASSO regression, and multivariate logistic regression. Five machine learning models-nomogram, back-propagation neural network (BPNN), random forest, gradient boosting, and support vector machine-were developed. External validation was performed using data from 289 patients at the First Affiliated Hospital of Guangxi Medical University.
resultsPE occurred in 71.0% of patients (1,405/1,979) within 3 days postoperatively. Independent risk factors included body mass index (BMI), carotid artery stenosis, postoperative pneumonia, duration of mechanical ventilation, intraoperative blood loss, operative time, and ejection fraction. Among the models, the BPNN demonstrated the best performance, with area under the curve (AUC) values of 0.828 in the training set and 0.751 in the internal validation set. The AUC for external validation was 0.737, outperforming the other models across all evaluation metrics.
conclusionsThis study developed a predictive model for post-CABG pleural effusion with high discriminatory power, providing a useful tool for early risk stratification in clinical settings.
