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
Mung bean (Vigna radiata L.) is commonly grown in Asia as an important nutritional dry grain legume, as it can survive better in arid conditions than other crops. Abiotic stresses, such as drought and high-salt contents, negatively impact its growth and production. The dehydration-responsive element-binding protein 2 (DREB2) transcription factors play a significant role in the response to these stress stimuli via transcriptional regulation of downstream genes containing the cis-element dehydration-responsive element (DRE). However, the molecular mechanisms involved in the drought tolerance of this species remain elusive, with very few reported candidate genes. No DREB2 ortholog has been reported for mung bean, and the function of mung bean DREB2 is not clear. In this study, a novel VrDREB2A gene with conserved AP2 domains and transactivation ability was isolated from mung bean. A modified VrDREB2A protein lacking the putative negative regulatory domain encoded by nucleotides 394-543 was shown to be localized in the nucleus. Expression of the VrDREB2A gene was induced by drought, high salt concentrations and abscisic acid treatment. Furthermore, comparing with the wild type Arabidopsis, the overexpression of VrDREB2A activated the expression of downstream genes in transgenic Arabidopsis, resulting in enhanced tolerance to drought and high-salt stresses and no growth retardation. The results from this study indicate that VrDREB2A functions as an important transcriptional activator and may help increase the abiotic stress tolerance of the mung bean plant.
