A 10-m resolution dataset of plastic-mulched farmland distributions on the Chinese Loess Plateau (2019-2021).
Article in Scientific data, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Plastic film mulching has been widely adopted to enhance crop yields in arid and semi-arid regions, but it has also resulted in severe environmental pollution and altered water and heat cycles in farmland ecosystems. However, the scarcity of training samples hinders large-scale mapping of plastic-mulched farmland (PMF) distributions. Here we generated the first 10-m PMF maps for the Chinese Loess Plateau spanning the period 2019-2021 (PMF-LP) by coupling the automatic training sample generation and classifier transfer methods. The resultant maps were validated using independent samples and showed satisfactory accuracies with F1-scores ranging from 0.80 to 0.86. The estimated PMF areas derived from the PMF-LP demonstrated good agreement with agricultural census data at the municipal level (R² ≥ 0.87). This is the first attempt to map PMF distributions at 10-m resolution on the Loess Plateau. The datasets generated in this study will be valuable for pollution assessments, yield forecasting, and greenhouse gas estimations.
