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
Protein tyrosine (Tyr) phosphorylation plays a central role in many signaling pathways leading to cell growth and differentiation in animals. Tyr phosphorylated proteins have been detected in higher plants, and the roles of protein Tyr phosphatases and protein Tyr kinases in some physiological responses have been shown. We investigated the involvement of Tyr phosphorylation events in abscisic acid (ABA) signaling using a pharmacological approach. Phenylarsine oxide, a specific inhibitor of protein Tyr phosphatase activity, abolished the ABA-dependent accumulation of RAB18 (responsive to ABA 18) transcripts. Protein Tyr kinase inhibitors like genistein, tyrphostin A23, and erbstatin blocked the RAB18 expression induced by ABA in Arabidopsis (Arabidopsis thaliana). Stomatal closure induced by ABA was also inhibited by phenylarsine oxide and genistein. We studied the changes in the Tyr phosphorylation levels of proteins in Arabidopsis seeds after ABA treatment. Proteins were separated by two-dimensional gel electrophoresis, and those phosphorylated on Tyr residues were detected using an anti-phosphotyrosine antibody by western blot. Changes were detected in the Tyr phosphorylation levels of 19 proteins after ABA treatment. Genistein inhibited the ABA-dependent Tyr phosphorylation of proteins. The 19 proteins were analyzed by matrix-assisted laser-desorption ionization time-of-flight/time-of-flight mass spectrometry. Among the proteins identified were storage proteins like cruciferins, enzymes involved in the mobilization of lipid reserves like aconitase, enolase, aldolase, and a lipoprotein, and enzymes necessary for seedling development like the large subunit of Rubisco. Additionally, the identification of three putative signaling proteins, a peptidyl-prolyl isomerase, an RNA-binding protein, and a small ubiquitin-like modifier-conjugating enzyme, enlightens how Tyr phosphorylation might regulate ABA transduction pathways in plants.
