Optimization of sustainable supply chains under uncertainty: integrating Internet of Things and blockchain.
Article in Scientific reports, 2026. 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
In today's competitive environment, emerging technologies such as the Internet of Things and blockchain can enhance transparency, traceability, and information management in supply chains. Based on this perspective, a multi-period and multi-product virtual closed-loop supply chain optimization model is developed. In this model, IoT and blockchain are incorporated as traceability and information-management infrastructures that facilitate product tracking and information transparency across the supply chain. The model is formulated as a mixed-integer linear programming model with a four-echelon forward structure and three-echelon reverse structure. Demand uncertainty is managed using a fuzzy approach. The problem is solved for small- and medium-scale instances using GAMS. For large-scale instances, due to NP-hard nature of the problem, the Grey Wolf Optimizer algorithm is used. To examine the role of Internet of Things and blockchain technologies in the supply chain, two comparative studies are conducted: the first study analyzes the simultaneous implementation of these two technologies. The second study focuses on the role of blockchain. The results of the comparative studies indicate that integrating the Internet of Things and blockchain enhances supply chain sustainability, transparency, and profitability.
