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
In Catharanthus roseus cell suspensions, expression of several terpenoid indole alkaloid (TIA) biosynthetic genes, including those encoding strictosidine synthase and tryptophan decarboxylase, is coordinately induced by fungal elicitors such as yeast extract (YE). This induction is mediated by several signaling steps including the biosynthesis of jasmonic acid, and the activation of the jasmonic acid-responsive ORCA transcription factors. We investigated a possible role of reactive oxygen species (ROS) as a second messenger in this system. YE was shown to activate the production of ROS, which was dependent on protein phosphorylation and calcium influx. However, ROS generation was neither necessary for the induction of genes involved in TIA biosynthesis by YE nor by itself sufficient to induce these genes. Therefore, we conclude that activation of the oxidative burst by YE occurs independently of the activation of genes involved in TIA biosynthesis.
