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

In recent years, quantity and quality of cultivated land in black soil region in Northeast China have changed with the continuous strengthening of the breadth and depth of land development, directly affecting food security in China. In this study, land-use data based on geo-information Tupu in 1990, 2000, 2010 and 2020 were selected and the spatiotemporal evolution of cultivated land in Northeast China was analyzed. Meanwhile, driving factors affecting the changes of cultivated land over the past 30 years was also explored. The results indicate that the net increase of cultivated land in the study area is 127.72 km
