A 40-year dataset of soil salinity dynamics (1985-2024) at 100 m resolution in the Western Songnen Plain, China.
Article in Scientific data, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
Soil salinization leads to land degradation, reduced agricultural productivity, and heightened food security risks. Accurate assessment of saline soil distribution and severity is critical for sustainable land management. However, challenges such as broad spatial extent, high heterogeneity, and limited field observations hinder mapping accuracy. Existing datasets in China show large discrepancies in salinized area estimates due to coarse spatial and temporal resolution. In this study, we classified soil salinity degree across the western Songnen Plain from 1985 to 2024 using field surveys, remote sensing imagery, and machine learning algorithms, achieving high accuracy (overall accuracy = 0.893, Kappa = 0.782). A regional soil EC prediction model (R
