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
Designing sustainable cement supply chains presents a complex challenge due to their high energy consumption, emission intensity, and sensitivity to uncertainty. This study proposes a novel bi-objective robust fuzzy Mixed-Integer Linear Programming (MILP) model to configure a microgrid-based cement supply chain that simultaneously considers environmental and economic objectives. The proposed model incorporates local renewable energy resources through microgrids to meet the significant electrical demand of cement production, while also embedding carbon emission caps and dust emission control across the network. To handle uncertainty in demand, energy cost, and emission parameters, a robust fuzzy programming approach is adopted. The model further applies the Weighted Sum Method (WSM) to obtain Pareto-optimal solutions and support multi-criteria decision-making. A realistic illustrative case demonstrates the applicability of the model, and sensitivity analyses reveal how key parameters such as income ratio and satisfaction level serve as powerful managerial levers. The model's ability to find optimal solutions in under two seconds underscores its computational efficiency. Overall, this research fills a critical gap by offering a comprehensive, uncertainty-aware, and sustainability-driven optimization framework for cement supply chains. The proposed framework offers practical decision-making tools for supply chain managers seeking to simultaneously reduce environmental impacts and ensure economic viability.
