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

Vegetation restoration is a critical strategy for combatting rocky desertification in the karst region. Soil black carbon (BC) contributes to the soil organic carbon (SOC) pool and plays an important role in carbon storage. However, the impact of vegetation restoration on BC accumulation under consistent geological (karst lithology) and climatic conditions is not well known. The distribution of BC in aggregates and its role in SOC also require clarification. We investigated the impact of vegetation restoration on soil aggregate stability and the micro-distribution of SOC and BC across a successional gradient (secondary forest, shrubland, farmland, and wasteland) in a karst rocky desertification area. Results showed that vegetation restoration significantly enhanced soil structural stability, with secondary forest and shrubland exhibiting the highest mean weight diameter (MWD) and geometric mean diameter (GMD). Compared with farmland and wasteland, the proportions of water-stable macroaggregates (> 0.25 mm) in secondary forest and shrubland areas increased to over 73%. SOC, BC and TCa concentrations were highest in secondary forest topsoil and decreased with increasing soil depth, while the BC/SOC ratio increased with depth, indicating the selective preservation of recalcitrant carbon in deeper soil layers. Macroaggregates are mostly responsible for SOC and BC accumulation in each land-type category. A significant positive correlation exists between aggregate stability, TCa and SOC and BC stocks (
