A linear programming framework for optimizing molecular combinations of asphalt four components.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
To enhance the efficiency and accuracy of asphalt molecular modeling, this investigation proposes a four-component molecular combination optimization method for asphalt based on linear programming. This method automatically selects the optimal representative molecular combination while satisfying multiple constraints, such as component ratios, element mass fractions, and hydrogen-to-carbon atomic ratio. Additionally, this investigation has developed a supporting graphical modeling system based on the PuLP library and Streamlit framework, featuring visual operations, flexible parameter configuration, and result export. Case studies demonstrate that the model output is highly consistent with experimental values, with all index errors within ± 2%. The system demonstrates well-fitting ability, solution stability, and engineering practicality, providing an efficient and intelligent solution for asphalt molecular simulation and formulation optimization.
