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

Black soils in Northeast China are among the most fertile globally, but have experienced significant degradation due to long-term intensive use of chemical fertilizers. Although organic amendments such as biogas slurry are considered promising alternatives, their effects on black soils in this region remain underexplored. In this study, a controlled pot experiment was conducted to evaluate the effect of biogas slurry on soil health, soil organic carbon (SOC), total nitrogen (TN), soil acidification, and soybean yield. In our study, biogas slurry was derived from cow dung. Four treatments were applied: no fertilizer (CK), chemical fertilizer (N), biogas slurry (BS), and mixed fertilizer (BS + N). Our study revealed that fertilizer application showed a significant (P < 0.05) impact on soil organic carbon (SOC) and total phosphorus (TP). The highest SOC (8.97 g/kg) and TN (1.30 g/kg) were observed under BS treatment. The soil pH was significantly (P < 0.05) higher under BS (6.69) and BS+N (6.64) than under N (6.40), indicating a buffering effect. Microbial biomass carbon (MBC) and nitrogen (MBN) were significantly enhanced under BS and BS+N, while N alone reduced MBN (
