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
Trehalose 6-phosphate (Tre6P) is a signalling metabolite that maintains sucrose homeostasis and links plant growth and development to the availability of sucrose. Most of our knowledge of the nexus between Tre6P and sucrose comes from studies on arabidopsis (Arabidopsis thaliana), and it is unclear whether this close relationship is generally conserved across other species. To address this question, we investigated the diel changes in sucrose and Tre6P in leaves from a phylogenetically diverse set of angiosperms with different phloem loading and carbohydrate storage strategies: arabidopsis, Alchemilla molis, strawberry (Fragaria×ananassa), Plantago major, melon (Cucumis melo), and wheat (Triticum aestivum). Despite large differences in their sucrose and Tre6P levels, there were positive correlations between sucrose and Tre6P across all species. Network analysis confirmed a strong association between Tre6P and sucrose in all species, and also revealed a common link with malate, consistent with positive regulation of malate synthesis by Tre6P. In combination with previous observations that Tre6P is synthesized in and around the leaf vasculature, our findings suggest that Tre6P primarily reflects the vascular transport pool of sucrose in leaves. We conclude that the sucrose-Tre6P nexus is widespread among angiosperms, with a conserved role in regulation of sucrose metabolism and transport.
