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
Rice false smut caused by Villosiclava virens is one of the destructive diseases on panicles of rice. Sexual development of V. virens, controlled by mating-type locus, plays an important role in the prevalence of rice false smut and genetic diversity of the pathogen. However, how the mating-type genes mediate sexual development of the V. virens remains largely unknown. In this study, we characterized the two mating-type genes, MAT1-1-1 and MAT1-1-2, in V. virens. MAT1-1-1 knockout mutant showed defects in hyphal growth, conidia morphogenesis, sexual development, and increase in the tolerance to salt and osmotic stress. Targeted deletion of MAT1-1-2 not only impaired the sclerotia formation and pathogenicity of V. virens, but also reduced the production of conidia. The MAT1-1-2 mutant showed increases in tolerance to salt and hydrogen peroxide stress, but decreases in tolerance to osmotic stress. Yeast two-hybrid assay showed that MAT1-1-1 interacted with MAT1-1-2, indicating that those proteins might form a complex to regulate sexual development. In addition, MAT1-1-1 localized in the nucleus, and MAT1-1-2 localized in the cytoplasm. Collectively, our results demonstrate that MAT1-1-1 and MAT1-1-2 play important roles in the conidiation, stress response, sexual development, and pathogenicity of V. virens, thus providing new insights into the function of mating-type gene.
