1 · What the graph read from it

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.

2 · The registry

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

Urban agglomerations regulate the balance between carbon sequestration supply and demand. This study examines carbon sequestration service flows across 19 Chinese urban agglomerations from 2000 to 2020 by integrating supply-demand assessment with circuit theory-based flow modeling. Carbon supply increased moderately, whereas demand rose rapidly, leading to persistent spatial imbalances. Supply is higher in western and southern regions, while demand concentrates in major eastern urban clusters. More than half of the agglomerations show supply surplus, whereas others remain balanced or deficit. Flow simulations reveal network structures in which ecological supply areas surround urban demand centers, with well-connected corridors in central and western regions and fragmented networks in the east. These results highlight the role of spatial connectivity in regulating ecosystem service redistribution and provide a basis for cross-regional ecological compensation and coordinated carbon governance.
