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
Introduction: Sand tube irrigation (STI) is one of the most considerable irrigation techniques for increasing water productivity in arid areas. However, it is unclear whether there is still room for further improvements in jujube yield and water productivity under STI with different irrigation and nitrogen application levels. Methods: To solve this problem, a two-year field experiment was conducted to investigate the effects of different irrigation and nitrogen applications on soil water storage, water consumption, jujube yield, and fruit quality, as well as water and nitrogen use efficiency under STI, and to determine the optimal irrigation and nitrogen application solution by the entropy weight-based TOPSIS method. Results: The results showed that irrigation very significantly ( Discussion: The research will provide technical support for the optimal agricultural water and nitrogen management of jujube in arid areas.
