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
Background: This study investigates pre- and intra-operative risk factors for re-operation after valve sparing aortic root replacement using the David technique to develop a risk model. Methods: A retrospective cohort study of two European centers, comprising data from 07/1993 to 01/2025 was performed. Follow up time was 120 (IQR: 141) months. Primary outcome was aortic valve re-operation. Prediction model was developed using uni- and multivariable logistic regression analysis. A risk score was derived. Calibration in the large and slope were performed. Receiver operating characteristic (ROC) analysis allowed discrimination assessment. Results: 1,074 patients were included. Male sex (OR: 1.98; 95% CI: 1.16-3.39, Conclusion: Bicuspid aortic valve, higher pre-operative AI, NYHA grade and male sex were independent risk factors for re-operation. Higher age and larger prosthesis sizes were protective factors. Further multi-center research is needed to validate and refine the prediction model.
