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
Decarbonizing materials production presents a major challenge to achieving a carbon-neutral society. The current carbon-neutral roadmap for materials generally assumes an uncertain dissemination of innovative production technologies, making the changes in material flows required for a carbon-neutral society unclear. This study introduces three material reduction scenarios and an input-output optimization model to explore material flows in Japan for achieving carbon neutrality by 2050 without disseminating innovative technologies. The results indicate that Japanese carbon emissions could reach neutrality by 2050 if the country can manage a yearly material reduction of 4% together with the decarbonization of electricity generation. To achieve this, the material efficiency of consumption must increase nearly 4-fold, and the material circulation rate must be doubled. Achieving such a rapid improvement in material efficiency and circularity is as challenging as the early large-scale deployment of material decarbonization technologies. Therefore, the critical choice in the remaining years is whether to bet heavily on innovative material decarbonization or prioritize technologies and policies accelerating material efficiency.
