The Coumarin Glucoside, Esculin, Reveals Rapid Changes in Phloem-Transport Velocity in Response to Environmental Cues.
Article in Plant physiology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers.
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
The study of phloem transport and its vital roles in long-distance communication and carbon allocation have been hampered by a lack of suitable tools that allow high-throughput, real-time studies. Esculin, a fluorescent coumarin glucoside, is recognized by Suc transporters, including AtSUC2, which loads it into the phloem for translocation to sink tissues. These properties make it an ideal tool for use in live-imaging experiments, where it acts as a surrogate for Suc. Here, we show that esculin is translocated with a similar efficiency to Suc and, because of its ease of application and detection, demonstrate that it is an ideal tool for in vivo studies of phloem transport. We used esculin to determine the effect of different environmental cues on the velocity of phloem transport. We provide evidence that fluctuations in cotyledon Suc levels influence phloem velocity rapidly, supporting the pressure-flow model of phloem transport. Under acute changes in light levels, the phloem velocity mirrored changes in the expression of
