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
Seedling deetiolation, a critical process in early plant development, is regulated by an intricate transcriptional network. Here, we identified VQ MOTIF-CONTAINING PROTEIN29 (VQ29) as a novel regulator of the photomorphogenic response in Arabidopsis (Arabidopsis thaliana). We showed that 29 of the 34 VQ proteins present in Arabidopsis exhibit transcriptional activity in plant cells and that mutations in the VQ motif affect the transcriptional activity of VQ29. We then functionally characterized VQ29 and showed that the hypocotyl growth of plants overexpressing VQ29 is hyposensitive to far-red and low-intensity white light, whereas a vq29 loss-of-function mutant exhibits decreased hypocotyl elongation under a low intensity of far-red or white light. Consistent with this, VQ29 expression is repressed by light in a phytochrome-dependent manner. Intriguingly, our yeast (Saccharomyces cerevisiae) two-hybrid, bimolecular fluorescence complementation, and coimmunoprecipitation assays showed that VQ29 physically interacts with PHYTOCHROME-INTERACTING FACTOR1 (PIF1). We then showed that VQ29 and PIF1 directly bind to the promoter of a cell elongation-related gene, XYLOGLUCAN ENDOTRANSGLYCOSYLASE7, and coactivate its expression. Furthermore, the vq29 pif1 double mutant has shorter hypocotyls than either of the corresponding single mutants. Therefore, our study reveals that VQ29 is a negative transcriptional regulator of light-mediated inhibition of hypocotyl elongation that likely promotes the transcriptional activity of PIF1 during early seedling development.
