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
MAIN
conclusionThis study identified and evaluated the expression of the AREB/ABF/ABI5 subfamily genes in chickpea and lentil, and revealed the major players involved in defense response to PEG-induced drought stress. Abscisic acid (ABA)-responsive element-binding protein/ABRE-binding factor/ABA-INSENSITIVE 5 (AREB/ABF/ABI5) subfamily proteins are major players in the ABA-mediated signaling pathway triggered by multiple stresses. AREB/ABF/ABI5 subfamily proteins belong to the basic-leucine zipper transcription factors that regulate the expression of several downstream defense genes to abiotic and biotic stresses. This protein set is highly targeted when trying to understand plant defense against abiotic stress or to improve plant tolerance to drought, cold, and salinity stresses. However, there is still very little information available about the genes of the AREB/ABF/ABI5 subfamily in chickpea and lentil. Herein, 8 chickpea and 9 lentil genes of the AREB/ABF/ABI5 subfamily were identified based on sequence analysis, and their expression levels were tested in a polyethylene glycol-induced drought experiment (20% PEG in Hoagland solution) using real-time RT-PCR and metadata analysis. Sequence analysis showed that members of this subfamily are highly conserved among themselves and with their orthologous genes in other closely related plant species. Overall, sequence data suggested that these genes may possess close or overlapping biological roles in regulating the transcription of abiotic stress-related defense genes. The meta-analysis from RNA-Seq datasets of unstressed plants showed that some members of this gene subfamily have a tissue-specific expression in both chickpea and lentil. Drought-contrasting chickpea and lentil cultivars showed that most AREB/ABF/ABI5 genes are modulated by PEG-induced drought. Furthermore, AREB/ABF/ABI5 genes had also a tendency for higher expression as cultivar tolerance increases. Therefore, this study identified the AREB/ABF/ABI5 subfamily genes in chickpea and lentil, and provides a comprehensive characterization of these members to support further focused research.
