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

Panax ginseng (C.A. Meyer) is an important medicinal plant cultivated under heavy shade, and stable production of high-quality roots requires appropriate nutrient management. Nitrogen (N) fertilization remains difficult to optimize because excessive N can promote shoot growth disproportionately, impair root development, and increase the risk of root quality deterioration and soil-related problems. We evaluated the response of two-year-old P. ginseng plants to four basal N application rates (0, 2, 4, and 8 g N m
