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
Rice (Oryza sativa cv. Dongjin) plants responded to treatment with methanol by inducing the synthesis of secondary metabolites such as serotonin derivatives which include feruloylserotonin and 4-coumaroylserotonin. This response was not only a dose dependence on methanol showing a maximum effect with 1% methanol concentration, but also methanol specific. No other solvents such as ethanol, atetaldehyde, isopropanol, formaldehyde, and formic acid showed the induced synthesis of serotonin derivatives as methanol did. The methanol induced synthesis of serotonin derivatives was completely blocked by the addition of abscisic acid (ABA), and significantly inhibited by the additions of zeatin and indoleacetic acid (IAA). However, gibberellic acid (GA) had little effect on the action of methanol. Finally, the induced synthesis of serotonin derivatives upon methanol treatment was closely associated with the transient increase in the activity of key enzyme of serotonin N-hydroxycinnamoyl transferase (SHT) which catalyzes the condensation of serotonin and phenolic-CoA into serotonin derivatives.
