Domestic wastewater is an overlooked source and quantity in global river dissolved carbon.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Riverine dissolved carbon (DC) plays a crucial role in global carbon cycle. Yet, the contribution of wastewater to global riverine DC remains unquantified. Here, we quantify the impact of treated and untreated domestic wastewater on dissolved inorganic carbon (DIC) and dissolved organic carbon (DOC) loadings at nation and river basin scales. We show that, globally, domestic wastewater discharges ~21.4 Tg DC annually-6.42 Tg DIC and 1.17 Tg DOC from treated, and 9.64 Tg DIC and 4.21 Tg DOC from untreated, collectively accounting for 3.13 ± 0.46% of the global riverine DC export. Contributions are highest in densely populated regions with high treatment capacity. Effluent DC levels are influenced by treatment technology, temperature, precipitation, economic growth and urban development. This underscores a need to incorporate the wastewater derived carbon into global carbon budget assessment, as well as to monitor and reduce carbon in wastewater effluents.
