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
Plant β-1,3-glucanases are involved in plant defense and development. In rice (Oryza sativa), 14 genes encoding putative β-1,3-glucanases have been isolated and sequenced. However, only limited information is available on the function of these β-1,3-glucanase genes. In this study, we report a detailed functional characterization of one of these genes, Osg1. Osg1 encodes a glucanase carrying no C-terminal extension. Osg1 was found to be expressed throughout the plant and highly expressed in florets, leaf sheaths, and leaf blades. Investigations using real-time PCR, immunocytochemical analysis, and a GUS-reporter gene driven by the Osg1 promoter indicated that Osg1 was mainly expressed at the late meiosis, early microspore, and middle microspore stages in the florets. To elucidate the role of Osg1, we suppressed expression of the Osg1 gene by RNA interference in transgenic rice. The silencing of Osg1 resulted in male sterility. The pollen mother cells appeared to be normal in Osg1-RI plants, but callose degradation was disrupted around the microspores in the anther locules of the Osg1-RI plants at the early microspore stage. Consequently, the release of the young microspores into the anther locules was delayed, and the microspores began to degenerate later. These results provide evidence that Osg1 is essential for timely callose degradation in the process of tetrad dissolution.
