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
Monosaccharide transporters mediate the membrane transport of a variable range of monosaccharides, which plays a crucial role in sugar distribution throughout the plant. To investigate the significance of monosaccharide transporters for rice (Oryza sativa L.) seed development, cDNA of a new putative monosaccharide transporter gene OsMST4 was isolated. The deduced OsMST4 protein shows typical features of monosaccharide transporters, and shares high homology with other plant homologues. Heterologous expression in yeast (Saccharomyces cerevisiae) showed that OsMST4 is a functional monosaccharide transporter capable of transporting glucose, fructose, mannose and galactose. Transcriptional analysis revealed that OsMST4 is expressed in all tested organs/tissues. In developing caryopses, its expression is high at the early and middle grain filling stages, and declines gradually to low levels after that. Further analysis revealed that it is expressed in both the maternal tissue and the filial tissue, with its highest expression in embryo. Cellular location in young caryopses through RNA in situ hybridization showed that OsMST4 mRNA mainly accumulates in the vascular parenchyma of the chalazal vein, cross-cells, nucellar tissue and endosperm. The expression pattern of OsMST4 was further confirmed by histochemical analysis of the OsMST4-promoter-beta-glucuronidase (GUS) transgenic rice plants. These data indicate that OsMST4 is actively involved in monosaccharides supply for seed development during the course of grain filling. In addition, the cell type-specific expression patterns of OsMST4 in other sink and source tissues were also investigated, and its corresponding physiological roles were discussed.
