Circulating biomarkers improve prediction of postoperative outcome after aortic valve surgery.

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: Predicting adverse outcomes following aortic valve surgery remains challenging. This study aimed to investigate the association between preoperative circulating biomarkers and postoperative mortality and morbidity, with the goal of improving established risk stratification tools. Methods: Between March 2018 and May 2022, 492 patients underwent surgical aortic valve replacement or repair and were included in a registry. Preoperative blood biomarkers, including hemoglobin, creatinine, high-sensitivity troponin I (hsTrop-I), GOT, GPT, INR, CRP, NT-proBNP and WBC, were sampled at baseline. Logistic regression analysis adjusted for EuroSCORE-II tested associations between biomarker levels and VARC-III adjudicated endpoints. Model fit was assessed using Akaike's Information Criterion, and likelihood ratio tests compared different prediction models. Results: Preoperative hemoglobin (OR 0.70; 95% CI: 0.57, 0.87; Conclusions: Combining established risk stratification models with preoperative biomarkers was associated with improved predictive performance for adverse outcomes after aortic valve surgery and may support heart team decision-making when choosing between surgical and transcatheter aortic valve replacement.
