The invisible subsoil compaction risk under no-till farming.

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
No-till (NT) is a key component of conservation agriculture aiming at producing crops with minimal soil disturbance. This land management practice offers numerous economic and ecological advantages over conventional tillage as evidenced by its rapid expansion since the 1960s, now practiced on 15% of the global arable land. Nevertheless, various crops exhibit persistent yield losses even decades after transition to NT. Here, we demonstrate that the promise of beneficial and sustainable soil management may be undermined by a gradual and invisible threat of subsoil compaction. We report on a risk of subsoil compaction stemming from the episodic passage of heavy machinery (e.g., harvesters). The threat is of dynamic and asymmetric nature whenever compaction events occur more frequently than the natural rates of soil structure recovery, resulting in a gradual increase in soil degradation. Our analyses show that nearly 40% of global NT lands (0.8 million km
