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
The actin-related proteins (ARPs) that are localized to the nucleus are present as components of various chromatin-modifying complexes involved in chromatin dynamics and transcriptional regulation. Arabidopsis (Arabidopsis thaliana) ARP7 is a constitutively expressed nuclear protein belonging to a novel plant-specific ARP class. In this study, we demonstrate a vital role for ARP7 protein in embryogenesis and plant development. Knocking out the expression of ARP7 in an arp7-1 T-DNA mutant produced morphologically aberrant, homozygous embryos that were arrested at or before the torpedo stage of development. Hence, the arp7-1 null mutation is homozygous lethal. Knocking down the expression levels of ARP7 protein with RNA interference produced viable Arabidopsis lines affected in multiple developmental pathways and induced dosage-dependent, heritable defects in plant architecture. The transgenic plants containing greatly reduced levels of ARP7 in the nucleus were severely dwarfed with small rosette leaves that are defective in cell expansion and trichome morphology. Moreover, the ARP7-deficient RNA interference plants exhibited retarded root growth, altered flower development, delayed perianth abscission, and reduced fertility. These pleiotropic phenotypic changes suggest a critical role for the Arabidopsis ARP7 protein in the regulation of various phases of plant development through chromatin-mediated, global regulation of gene expression.
