China material stocks and flows account for 2019-2023.
Article in Scientific data, 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
China is the world's largest consumer of bulk materials, and the accumulation of material stocks and flows plays a critical role in shaping its socioeconomic metabolism and environmental sustainability. Detailed and up-to-date provincial-level data on material stocks and flows are therefore essential for understanding resource use and supporting regional sustainability transitions. This study presents the most recent update of the Provincial Material Stocks and Flows Database (PMSFD), extending our previous dataset for 1978-2018 to cover the years 1978-2023. The PMSFD provides consistent time-series data for 31 provinces and 13 bulk material categories across five key end-use sectors, compiled using a bottom-up material flow analysis framework that integrates official statistics and standardized estimation methods. Compared with the earlier version, the updated PMSFD captures the recent slowdown in material accumulation and reveals the regional heterogeneity. The data can be applied to studies on material metabolism, resource efficiency, circular economy strategies, and embodied carbon emissions accounting, as well as to inform regional and national sustainability policymaking in China.
