Extent of sediment concentration trends associated with climate and human factors across global rivers.
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
Suspended sediment concentration (SSC) is a key indicator of river ecosystems, influencing aquatic habitat quality, biogeochemical cycling, reservoir sustainability, and the persistence of downstream coastal land. Despite its global significance, long-term assessments of SSC trends have been limited in spatial scope. Leveraging > 88,000,000 satellite-derived SSC estimates, we analyzed trends over a 38-year period (1984–2022) across > 200,000 river segments globally. Our analysis reveals significant SSC trends in one-third of rivers, with 27% exhibiting declines and 7% showing increases. Basins with more widespread declining SSC trends are in temperate and arid regions and the extent of change is primarily associated with dam regulation and forest recovery. In contrast, increasing trends are concentrated in tropical basins, where deforestation and high rainfall causes erosion. These findings highlight the value of a spatially and temporally coherent, global riverine SSC database for documenting and pinpointing environmental change in unmonitored rivers.
