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

To clarify the responses of soil carbon and nitrogen to biochar amendment under deficit irrigation, a two-year field experiment was conducted in wheat fields of northern Xinjiang with a completely randomized block design. Four biochar rates (0, 10, 20, 30 t/ha, namely B0-B3) and three irrigation regimes were set. Irrigation volumes were 4500, 4050 and 3600 m
