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
Objective: This study explores the application of Eurasian eagle-owl wing characteristics to the design of folding wings for flying cars. By analyzing the aerodynamics of the eagle-owl wing, we aim to innovate folding wing configurations to improve lift, reduce drag, enhance flight stability, and ultimately increase the overall energy efficiency and safety of flying cars. Methods: First, a comparative analysis of aerodynamic performance data across multiple owl species was conducted, leading to the selection of the Eurasian eagle-owl wing as the bionic prototype. Then, reverse engineering modeling was performed using image-based photogrammetry. A three-dimensional shape error measurement method was applied for quantitative error analysis of the reconstructed model. High-precision point cloud data of the wing were obtained and sliced at equal intervals. The extracted airfoil cross-sections were fitted using polynomial equations and simulated in XFOIL. Sections exhibiting superior aerodynamic performance were selected as bionic airfoils. Next, using coupled extension analysis method and a comprehensive coupling degree evaluation function from coupled bionics, the coupling bionic feature vectors and eigenvalues between the folding wing and the bionic reference were analyzed. A coupled extension matrix model was established to guide the bionic design based on eagle-owl wing morphology. Finally, fluid simulations were performed using Fluent software, and a comparative analysis of aerodynamic performance was conducted. Results: The results reveal that the folding wing design inspired by the Eurasian eagle-owl significantly improves lift, reduces drag, and enhances flight stability compared to traditional wing designs. Conclusion: The bionic design of flying car folding wings based on the Eurasian eagle-owl wing proves effective in enhancing aerodynamic performance.
