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
Although a large number of embryo mutants have been studied, mostly at the morphological level, the critical molecular and cellular events responsible for embryogenesis are unknown. Here, we report that using an enhancer-trap embryo mutant of Arabidopsis, we identified a gene, ROOT-SHOOT-HYPOCOTYL-DEFECTIVE (RSH), that is essential for the correct positioning of the cell plate during cytokinesis in cells of the developing embryo. We traced the earliest point of influence of RSH to the first asymmetrical division of the zygote. Homozygous rsh embryos were defective morphologically, had irregular cell shape and size, and germinated to form agravitropic-defective seedlings incapable of further development. The RSH gene encodes a Hyp-rich glycoprotein-type cell wall protein. RSH localized to the cell wall throughout the embryo and to a few well-defined postembryonic sites. Although several lines of evidence from previous work suggest that the cell wall is involved in development, the protein(s) involved remained elusive.
