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

Understanding the redistribution of soil organic carbon (OC) driven by erosion contributes to the global carbon budget and watershed management. Quantifying the sources of eroded OC in sediments provides new insights to addressing this issue. However, limited quantitative information on the factors influencing OC sources has constrained the behavior of regulating the OC exported from the watershed. Here, we explored the sources of OC in lake sediments over the last 100 years and quantified the effects of climate change and human activities on OC sources. Results from the stable isotope fingerprinting and MixSIAR model indicated that phragmites (30.34%) and croplands (21.48%) were consistently the main OC sources. Therefore, efforts should be concentrated on controlling soil erosion from cropland and managing the endogenous environment. In addition, the partial least squares pathways (PLS-PM) and random forests revealed that human activities (Path coefficients (r
