1 · What the graph read from 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.

2 · The registry

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

Background: The incidence of cardiac surgery-associated acute kidney injury (CSA-AKI) is 26.0%-28.5%. Among cardiac procedures, off-pump coronary artery bypass grafting (OPCABG) is a major contributor to CSA-AKI. Early detection and prompt intervention for high-risk patients are crucial. We therefore developed a machine learning model to predict OPCABG-associated acute kidney injury (AKI), aiming to inform perioperative clinical decision-making. Methods: This retrospective study analyzed 938 patients who underwent OPCABG from June 2023 to January 2025. We preprocessed baseline and intraoperative time-series data separately. Using Tsfresh in Python, we extracted time-series intraoperative features, which were then integrated with selected features for model retraining. The final OPCABG-AKI risk prediction model was established by selecting the optimal model based on accuracy and AUC metrics. SHAP analysis was employed to rank feature importance and identify key risk factors. Results: Of the 938 patients, 210 (22.39%) developed OPCABG-AKI. The XGBoost model outperformed others in predicting OPCABG-AKI, achieving an AUC of 0.982, accuracy of 0.916, and precision of 0.983 in external validation. SHAP analysis identified Cystatin C (Cys-C) as the top predictor, with NT-proBNP levels ranking second. Conclusions: The XGBoost model showed outstanding performance in predicting OPCABG-AKI. Selecting features from preoperative data and integrating them with intraoperative data significantly improved prediction accuracy. This model enables clinicians to stratify patient risks and make informed decisions regarding OPCABG-AKI, promoting early patient recovery.
