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

Background: Currently, low-cost food production using little or no fertiliser is common in oasis dry farming in Xinjiang. This approach results in excessively low crop yields and resource utilisation. Given the limited local precipitation, optimising fertiliser application to improve crop yields, water use efficiency (WUE), and nitrogen use efficiency (NUE) is key. However, the effects of manure and topdressing nitrogen (N) fertiliser on the yields, WUE, and NUE of dryland wheat in the Xinjiang Oasis region of China have not been studied sufficiently. Methods: Therefore, we conducted a 2-year field experiment that examined manure (0 and 30 t ha Results: Compared with application of chemical N alone, combination with manure increased leaf area index (LAI) and aboveground biomass (ABG) values, and crop NUA. Soil water storage (SWS) increased with soil depth and was 27.5-55.2% higher in the upper soil layer than in the deeper layer. The high evapotranspiration (ET Conclusions: Therefore, we suggest that the combination of 30 t ha
