The risk factors and implications of noninfectious fever after surgery for acute type A aortic dissection.

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: Postoperative fever is common after aortic surgery and often leads to concerns about infection. However, fever may also arise from noninfectious inflammatory responses. The aim of this study was to identify the risk factors and implications of noninfectious fever in patients undergoing surgery for acute type A aortic dissection (AD). Methods: This retrospective analysis examined 636 patients who underwent aortic replacement for acute type A AD between 2003 and 2024. Patients were excluded if they had pre- or postoperative infections. The remaining 545 patients were divided into a "Non-fever" group and a "Noninfectious fever" group. Patient demographics, surgical details, and outcomes were compared. Multivariable logistic regression was performed to identify independent predictors of noninfectious fever. Results: Patients with noninfectious fever were younger (63.3±14.8 Conclusions: Younger age, longer CPB time, and complete false lumen thrombosis were independent risk factors for noninfectious postoperative fever following type A AD surgery. Recognizing this benign response could help to avoid unnecessary testing and antibiotics, which would improve postoperative care and resource utilization.
