Plant hormone conjugation: a signal decision.
Article in Plant signaling & behavior, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
Tight regulation of the auxin hormone indole-3-acetic acid (IAA) is crucial for plant development. Newly discovered IAA antagonists are the amide-linked tryptophan conjugates of IAA and jasmonic acid (JA). JA-Trp and IAA-Trp interfered with root gravitropism in Arabidopsis, and inhibited several responses to exogenously supplied IAA. Relatively low concentrations of the inhibitors occurred in Arabidopsis, but Pisum sativum flowers contained over 300 pmole g(-1) FW of JA-Trp. DihydroJA was an even more effective inhibitor than JA-Trp, suggesting that Trp conjugates with other JA derivatives may also be functional. JA-Trp and IAA-Trp add to the list of documented bioactive amide hormone conjugates. The only other example is JA-Ile, the recently discovered jasmonate signal. These examples establish that conjugation not only inactivates hormones, but in some cases creates novel compounds that function in hormone signaling.
