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

Changes in land use and land management can have significant effects on the global emissions budget, influencing the climate through biogeochemical processes. However, their impacts on major soil greenhouse gas (GHG) emissions in West Africa remain poorly documented and understood. This study provides the assessment of soil GHG emissions in the Sudanian savanna region of West Africa using a chamber-based experimental setup. The measurements are taken at four sites with contrasting land use and land management practices: pristine savanna forest, cropland, degraded grassland, and a rainfed rice field. Over two consecutive years (2023-2024) of weekly chamber measurements during the rainy season (corresponding to the rice-growing period), our results reveal significant variation in methane (CH
